and
Cautions
WARNING

Describes a potential hazard which could result in injury or death, or, a procedure
which, if not performed correctly, could result in injury or death.

!

CAUTION

Describes a procedure which, if not performed correctly, could result in damage
to data, equipment, or systems.

Power
Supply
Safety
WARNING—High Energy and High Voltage

Exercise caution when using and calibrating a power supply. High energy levels
can be stored at the output voltage terminals on a power supply in normal
operation. In addition, potentially lethal voltages exist in the power circuit and on
the output and sense connectors of a power supply with a rated output greater
than 40 V. Filter capacitors store potentially dangerous energy for some time after
power is removed.

!

vi

CAUTION

Operate the power supply in an environment free of flammable gases or fumes. To
ensure that the power supply’s safety features are not compromised, use the
power supply as specified in this manual and do not substitute parts or make any
unauthorized modifications. Contact the service technician for service and repair
help. Repairs must be made by experienced service technicians only.
CAUTION

For Use as a Battery Charger
When you are using any of these power supplies for battery charging applications,
it is essential to provide an appropriately sized fuse or circuit breaker in series
between the power supply output and the battery.
Installation of a protector (fuse or DC circuit breaker) rated for about 115% of the
maximum current rating of the power supply and designed specifically to interrupt
the DC voltage of the battery, will provide adequate reverse polarity current
protection. Where several power supplies are in parallel, it is best to fuse each one,
rather than one large fuse for all.

About The XDC Power Supply
Overview of Operation

Overview of Operation
Power ON Power ON describes the period between the time the AC power is turned ON and the
time the power supply is ready for normal operation. Each supply comes with a
series of factory default settings that may be in effect at the conclusion of the Power
ON period. These include:

•
•
•
•

Output OFF: No current is sent to the DC output connections. You must press
Out ON/OFF to activate the supply output.
Voltage 0V: The Voltage setpoint is zero.
Current 0A: The Current setpoint is zero.
Local mode operation

The output state depends on the Power ON output setting. You can customize the
Power ON settings to suit your needs. See “Configure Power ON Settings” on page
84 for more information.
Control One local method and 4 remote methods are available for controlling the power

Load Wiring

Load Wiring
When connecting load wiring to the power supply, consider the following factors:

•
•
•

Current carrying capacity of the wire
Maximum load wiring length for operation with sense lines
Noise and impedance effects of the load lines

Current As a minimum, load wiring must have a constant capacity greater than the output
Carrying current rating of the power supply. This ensures that the wiring will not be damaged
Capacity even if the load is shorted. Table 2.4. shows the maximum current rating, based on
450A per square centimeter, for various gauges of wire rated for 105°C operation.
Operating at the maximum current rating results in a temperature rise of
approximately 30°C for a wire operating in free air. Where load wiring must operate
in areas with elevated ambient temperatures or bundled with other wiring, use larger
gauges or higher temperature-rated wiring. For high current applications,
custom-designed bus bars are typically used. To increase the current carrying
capability, use parallel cables.

Length for
Operation
with Sense
Lines

For applications using remote sensing, or for improved voltage regulation at the load,
you must limit the voltage drop across each load line. We recommend that you use
the larger load wiring to ensure a smaller voltage drop (1V maximum), although
units will compensate for up to 5V drop in each line with the remote sense lines
connected.

Noise and To minimize noise pickup or radiation, use the shortest possible length of
Impedance shielded-twisted pair wiring for load lines. Connect the shield to the chassis via a rear
Effects panel mounting screw. Where shielding is not possible or is impractical, twisting the
wires together offers some noise immunity. When using local sense connections, use
the largest practical wire size to minimize the effects of load line impedance on the
regulation of the supply.

WARNING
Exercise caution when operating the power supply. High energy levels can be stored
at the output terminals on a power supply in normal operation. In addition, potentially
lethal voltages exist in the power circuit and on the output and sense connectors of a
power supply with a rated output greater than 40V. Filter capacitors store potentially
dangerous energy for some time after power is removed.

!

CAUTION
When making connections to the bus bars, ensure that each terminal’s mounting
hardware and wiring assembly are placed to avoid touching the other terminal and
shorting the power supply outlet. Heavy connecting cables must have some form of
strain relief so they don’t loosen the connections or bend the bus bars.

Make load connections at the rear of the power supply at the positive and negative
output bus bars or to the 4-terminal wire clamp connector, depending on the model.
(See Figure 2.7.)
Wire Size The wire should be one size larger than necessary to accommodate the required
output current. Normally, the next largest commonly used gauge is used. For
example, use 10AWG for 20A, and 8AWG for 30A.
Isolation The wire must have a suitable insulating coating that will prevent arcing between the
positive and negative output current, and must be rated for 105°C operation.

Single Load To connect a single load to the DC output bus bars (10–150V outputs):
1. Ensure that the power supply is powered OFF.
2. Place a bolt in the connecting hole of the negative bus bar, and fasten the
negative wire or bus bar, a washer, and a nut to the bolt.
3. Using a wrench, turn the bolt until it is secure at approximately 25 foot-pounds

4. Fasten the positive wire or bus bar to the positive bus, using a bolt, washer, and
nut.
5. Tighten the bolt to approximately 25 foot-pounds (34Nm).
6. Ensure that the positive and negative wires are arranged so bare wires do not
come into contact with each other or the chassis.

Multiple To connect multiple loads in parallel:
Loads • Follow the “Single Load” procedure with the following exception:
• To minimize interaction between loads, bring the wiring for each load directly
back to the supply output. When each load to the power supply is wired
separately, the loads will see only the precisely regulated output from the supply.
If 2 loads share a single cable, the fluctuation in current to one load will cause
the voltage to vary on the others. This is due to wire impedance drops.

Installation
Remote Sensing

Remote Sensing
The power supply regulates the output voltage at the output connectors in its normal
configuration without remote sense lines connected.
Remote sensing lets the power supply track and regulate the output voltage at the
load, and thereby compensate for the voltage drop in the load lines. The power
supply will only compensate within the limitations of its voltage rating, to a
maximum of 5V per load line. Remote sensing is normally only required for critical
loads which cannot tolerate the slight voltage drop in the load lines caused by their
resistance. Remote sensing has no effect when the power supply is operating in
Constant Current mode.
Two remote sensing connectors are located on the rear panel of the power supply.
See “Rear Panel” on page 30 for location and polarity. Connect 2 wires from these
ports to the load, where the power supply cables terminate for your connection.
Carefully observe the correct polarity when making the connection. On 12000 Watt
units, connect the sense wires to the connector on the top or master power module.
The remote sensing input is sensitive to electrical noise, so always use a shielded
twisted pair, 22AWG or greater for the sense line cable. Terminate the shield to the
supply chassis or the negative output of the power supply for best results.

of the Power-On period, the supply is normally in its default Power-On mode with
the output OFF, VSET=0 and ISET=0.
Output In this state, the output is disabled and there is no output regardless of power settings.
Shutdown The power supply can be placed in the Output Shutdown state by a command (via
the front panel or from the programming interface), via the Interlock signal, or from
a protection mechanism. This is also called the Standby mode.
Soft Start In this state, the output power is ramping up gradually towards its target load. This
reduces equipment stress. This state occurs whenever the supply output is set to ON
or a protection state is re-set, and is approximately 2 seconds in duration.
Normal This is the normal operating state for the power supply. The power supply is ready
Operation to accept commands.
Calibration This is a service mode that is used to calibrate setpoints and readback levels for
accuracy. Calibration should only be performed by qualified service personnel. For
detailed information, see Appendix A.

Remote Analog Operation
Analog The analog interface has 2 ports: the user lines and the analog programming lines.
Connections The tables below show the function and power flow for each pin on these ports.
The user lines are optically isolated. The output lines are open collector
configuration. The input lines are capable of sinking 10mA (with recommended 5V
at input) up to a maximum 90mA.
The analog program and monitor lines are fully isolated from the supply output, but
not each other. Use precision variable low noise voltage sources for the program
lines, and be sure that the program source ground potential is the same as on the
analog readback circuitry.
The external analog monitoring circuitry must be high impedance because the
onboard V and I readback sources have approximately 300 ohms output impedance.
Connect your program and readback lines to the removable wire clamp connectors
marked “user lines” and “program lines” in Figure 4.1. Strip 0.2” (5mm) of
insulation from the wires and clamp securely at the appropriate pin. See Table 4.1,
Figure 4.1 and Table 4.2 for the location and function of each connector.
Use shielded twisted pairs of 22–24AWG for signal connections.

Multichannel Operation (6000 Watt only)

Multichannel Operation (6000 Watt only)
Multichannel Multichannel operation is only available for 6000 Watt units. You may remotely
Connections control up to 50 power supplies from one programming interface (RS-232 or GPIB)
by using multichannel addressing if the CANbus option is installed.
One power supply will be connected to a PC via RS-232 or GPIB. All other power
supplies are connected via CANbus (Controller Area Network) to that unit. SCPI
commands that include a channel address will be sent via the CANbus to the other
power supplies. (Commands with the local address will be executed locally and will
not be sent).
The multichannel address must be appended to the program mnemonic. If no
multichannel address is appended to the program mnemonic, the command is
executed by the local (directly connected) power supply.
Each unit of the network can send and receive commands to and from other units on
the network. It is highly recommended that only one command be sent at a time. Any
RS-232 and GPIB timeout settings should be increased when using multichannel
commands.
CANbus

The CANbus port is a one male, one female DB9 connector to support “daisy chain”
connections. The CAN (Controller Area Network) is an ISO standard (ISO11898)
for a serial communication network. Table 4.5 describes the pin functions. Pins 1, 4,
8, and 9 are not used. The CANbus is used for communications in multichannel
operation or current sharing (master/slave) operation, and is part of the optional
GPIB/CANbus interface card.

Remote Operation
Multichannel Operation (6000 Watt only)

Configuration Before connecting a power supply to a multichannel network, you must configure
each power supply with a unique address. The front panel or a remote interface
maybe used to do this.
One power supply must be configured to operate via RS-232 or GPIB.
Front Panel

1. Select the "REMOTE CONFIG" menu
2. Select the "Multichnl Cfg" menu. Press ENTER.
3. When prompted with "Addr" enter a unique network address in the range 1–50.
Press ENTER
To receive and execute commands:
1. Select the "REMOTE SELECT" menu, then select "Multichannel" from the
list. Press ENTER.
SCPI

Set a slave's multichannel address using the command:
SYSTem:COMMunicate:MCHannel:ADDRess

where multichannel-address is an integer in the range of 1-50, and the command is
sent via a controller directly connected to the slave’s RS-232 port.
If the unit is to execute commands, set the power supply to accept control via
multichannel commands (the CANbus interface) with the SCPI command:
SYSTem:REMote:SOURce MCHannel
Setup 1. Connect power supplies to be controlled via the CANbus network. Parallel male
DB9 to female DB9 cables (N-1) are required. Connect the power supplies in
series, linking the first power supply to the second using one cable, and then the
second to the third using a second cable and the second CAN port. A single
ribbon cable with multiple connectors may be used instead of several cables for
ease of connection. Terminate the bus at both ends with 120 ohm, 1/4 Watt
resistors (included) across the CAN HI and CAN LO signals (Pins 2 and 7). See
Table 4.5, “CANbus Pins,” on page 113.

2. At least one power supply should be connected to a PC via RS-232 or GPIB for
multichannel functionality. Configure each of the power supplies with a unique
address, as described in the configuration section. Addresses may be in the range
1 to 50 inclusive.
3. Turn the power supplies on one at a time, setting the remote control source of
each power supply which will accept commands to "multichannel."
See Figure 4.3.

Figure 4.3 Connections for Multichannel Operation

Using Once the power supplies have been configured and connected, you may power them
Multichannel on.
Operation
Power supplies controlled via multichannel have full capabilities, including
changing REM/LCL modes and calibration.
Any power supply may send multichannel commands, if they are connected to a PC
via RS-232 or GPIB.
A power supply will attempt to connect to the network:

•
•

Release 3.0

on power up, and
when the multichannel address is changed.

115

Remote Operation
Multichannel Operation (6000 Watt only)

Note that slave units have an automatic readdressing capability when in multchannel
mode. A slave unit will attempt another address when it is added to a string with an
address that is already taken. If no new address can be found then the following error
will be queued:
Error 1702, “Multichannel address taken” is queued if the power
supply fails to connect.
SCPI Remote Control (RCONtrol) subregister will indicate the status of the
connection. A power supply that has been disabled will not have any bits set. Use the
SCPI command:
STAT:OPER:RCON:COND?
to query the condition of the multichannel interface.
See Table 4.13, “Remote CONtrol Sub-Register,” on page 148 for a description of
the bits in this register.
Multichannel To send a command to a multichannel power supply, attach the channel address to
Commands the command. If no channel number is specified, the command will be executed by
the directly connected power supply.
For example, the command:
SOURCE12:VOLT 10.0
will set the power supply with address 12 to 10V output. The master receives the
command and puts in on the CANbus.
Appendix B. “SCPI Command Reference” lists all commands.
[]indicates where the multichannel address is to be inserted into the
command.
IEEE488.2 commands have been given an alias that is SCPI compliant if the
command is applicable to a power supply in multichannel operation. These
commands include *CLS, *IDN?, *OPT?, *RST, *TST?, *RCL, *SAV, *SDS, and
*WAI. See Table B.9, “System Commands,” on page 204.

Triggering Triggers are event-driven signals that instruct power supplies to change their output.
Commands Triggering provides a method to control changes in the power supply’s output and to
program several power supplies to react at the same time. Triggering is useful in
manufacturing processes where power requirements change as the machinery
performs different operations.
CAUTION
Setpoint limits do not apply to triggered setpoints.

!

To program triggers:
1. Configure the desired output levels as a result of a trigger.
VOLTage:TRIGgered {|MAX|MIN|DEF}
CURRent:TRIGgered {|MAX|MIN|DEF}
POWer:TRIGgered {|MAX|MIN|DEF}

The user can choose to set all or any one of voltage, current, and power triggered
levels.
DEF (DEFault) means that when a trigger is received, no change will occur.
2. Specify a trigger signal source.
TRIGger:SOURce {BUS|EXT|IMM|NONE} Where:

•
•
•
•

BUS means the trigger source is the IEEE 488.1 GET or “*TRG”
EXT means the source is the external trigger line
IMM means the trigger source is the SCPI command INIT:IMM
NONE means triggering is disabled. See , p. 109.

Auto Auto Sequencing allows users to program a sequence of steps. Each step has the
Sequencing properties of voltage, current, power limits, and OVP limit. The steps are either
programmed to run for a predetermined length of time or are programmed to pause
and wait for a trigger.

!

CAUTION

Setpoint limits do not apply to auto sequence programmed setpoints.

Programmed sequences can run one time only, or repeatedly up to 9999 times or
infinitely. You can store up to 10 sequences of 99 steps each. The duration of each
step may range from a minimum of 10 milliseconds to a maximum of 99 hours.

Operation

Users can select and start a sequence, and while the sequence is running, pause or
end it. Users can press and hold the TRIGGER button to skip over steps that have a
set duration.
Commands are also available to let users run, pause, resume, and restart an
autosequence. A pause, or wait for trigger, causes the power supply to hold the
output at the programmed level until the appropriate signal to continue is received.
Editing

Users can delete single steps or entire sequences. If a step is deleted, the subsequent
steps will shift up. If a new step is inserted, the subsequent steps will shift down.
Remote programming of auto sequences has the same functionality as using the front
panel.

Slew Rate The slew rate is calculated as a function of change in the output voltage and a given
time interval. The maximum slew rate is 1% V rating/150us. The slew rate is saved
upon power off and restored at power on. Output ON/OFF and shutdown are not
affected by the programmable slew rate. These functions have a slew rate of
1%/20ms. For more information on setting slew rates, see “Slew Rate” on page 102.
The SCPI commands for changing the voltage slew rate are:
:VOLT:SLEW:STEP { | MAX | MIN | DEF}
where voltage-step has the units V, mV, etc.
and the range is 0.1% to 5% of rated voltage.
default step is 0.1% of rated output voltage.
:VOLT:SLEW:INTerval { | MAX | MIN | DEF}
where time interval has the units s, ms, or us
and the range is 150 us to 1.5s
default interval is 150us.

!

CAUTION
Check both the voltage step and the interval to ensure you get the required slew rate.

The combination must not exceed 1% V rating/150us. Though the software will
attempt to achieve higher slew rates, it is limited to this value by hardware
constraints. Manufacturer's recommendation is to keep the slew rate at or below the
default value.
Example:
Set a slew rate of 100V/10s for a 100V-60A power supply.
This slew rate is 1V/0.1s, which is within the acceptable range.
Send the commands:
":VOLT:SLEW:STEP 1", and
":VOLT:SLEW:INT 100ms"

include others in the future. A zero will be returned if no options are installed.
Example:
*OPT? may return "GPIB, CANBUS" to indicate that both the GPIB and CANbus

SCPI Version SYST:VERS?
Query

Status The Status Register structure is mandatory for SCPI and IEEE 488.2 compliance.
Registers The register bits are defined by the SCPI and IEEE 488.2 standards.
Each status register has a Condition, Event, and Enable register and transition filters.
See “Status Register Commands” on page 157 for commands to read or change their
values.
Condition Register

Transitions of the condition register are automatic and reflect the condition of the
instrument at the moment. Reading a condition register has no effect on the contents.
Event Register

The event register bits are set automatically to correspond with changes in the
condition register. The rules are dependent on the positive and negative transition
registers. Reading an event register clears it. The *CLS command clears all event
registers.

142

Operating Manual for XDC Series Power Supply

Remote Operation
SCPI Commands for Digital Interfaces

Enable Register

The enable register enables reporting of the event bits to the summary bit or the status
byte. The contents of the enable register are unchanged by *CLS and *RST.
Transition Filters

A positive transition filter allows an event to be reported when a condition changes
from false to true. Setting both positive and negative filters to TRUE allows an event
to be reported any time the condition changes. Clearing both filters disables event
reporting.
The contents of transition filters are unchanged by *CLS and *RST.
The status registers maybe be divided into 4 categories, the operation status registers,
the questionable status registers, the standard event status register and the status byte.
OPERation Status Register

The operation status register is a 16-bit register which contains information about
conditions which are part of the power supply’s normal operation.
The Operation Status data structure has the operation status register and 5
sub-registers to represent regulation, shutdown, protection shutdown, remote
control, and current sharing modes. Each of the sub-registers is summarized in a
summary bit.
Figure represents the Operation Status data structure. The “+” represents the logical
summation of bits in a register. Table 4.9, Table 4.10, Table 4.11, Table 4.13, and
Table 4.14 describe the meanings of each bit as well as the bit number and bit weight.

QUEStionable Status Register

The Questionable Status Register is a 16-bit register that stores information about
questionable events or status during power supply operation. That is, bits in these
registers may indicate that the output of the supply is of undesirable or questionable
quality.
The Questionable Status data structure consists of a questionable status register and
4 sub-registers representing the status of the voltage, current, power outputs and
temperature.
Figure gives an overview of the Questionable Status data structure. The “+”
represents the logical summation of bits in a register. Table 4.15, Table 4.16, Table
4.17, Table 4.18, and Table 4.19, describe the meanings of each bit as well as the bit
number and bit weight.

Status Byte

The Status byte register contains the STB and RQS(MSS) messages as defined in
488.1. The user can read the status byte register using a 488.1 serial poll or the 488.2
*STB? common command. If the user sends a serial poll, bit 6 will respond with
Request Service (RSQ). The value of the status byte is not altered by a serial poll.
The *STB? query causes the device to send the contents of the Status Byte Register
and the Master Summary Status (MSS) summary message. The *STB? query does
not alter the status byte, MSS, or RQS.

SCPI Status Commands
Preset Status
Configures the status data structures to ensure that certain events are reported at a
higher level through the status-reporting mechanism. These events are summarized
in the mandatory structures, the Operation Status Register, and Questionable Status
Register.
The PRESet command affects only the enable registers and the transition filter
registers of the status data structures. PRESet does not clear any of the event registers
or any item from the error/event queue. The *CLS command is used to clear all event
registers and queues in the device status-reporting mechanism.
For the device-dependent status data structures, the PRESet command sets the enable
register to all 1s and the transition filter register to report only positive transitions.
For the SCPI mandatory status data structures, the PRESet command sets the
transition filter registers to recognize only positive transitions and sets the enable
register to 0s. The following will not be affected by this command: Service Request
Enable Register, Parallel Poll Enable Register, the memory register associated with
the *SAV command, the power supply address, Output Queue, and the
power-on-status-clear flag setting.

The Event Summary Enable command determines which bits in the Standard Event

The Power-on Status Clear command determines if the Standard Event Status Enable
Register is cleared at power-on.
E.g.
Sending "*ESE 16" sets bit 4 of the Standard Event Status Enable Register. This will

Service Request Enable Register

The Service Request Enable Register allows the user to select the reasons for the
power supply to issue a service request. The Service Request Enable Register allows
the user to select which summary messages in the Status Byte Register may cause
service requests.
To clear the Service Request Enable Register send "*SRE 0." The Power-on Status
Clear command also determines if the Service Request Enable Register is cleared at
power-on. A cleared register does not allow status information to generate a service
request.
E.g.
Sending "*SRE 8" sets bit 3 of the Service Request Enable Register. This will cause
the Summary bit of the Questionable Status register (bit 3) in the Status Byte to
generate a service request message whenever it gets set.
Command: *SRE , *SRE?
SCPI equivalent for multichannel use:
STATus[]:SREQuest:ENABle

Parallel Poll Enable Register

Each of the 16 bits in the Parallel Poll Enable register correspond to bits in the Status
Byte. Each bit in the Parallel Poll Enable register is ANDed with its corresponding
bit in the Status Byte and the resulting bits are ORed together to generate ist.
Therefore using the parallel poll enable register allows any single bit or combination
of bits to control the ist message.
The Power-on Status Clear command determines if the Parallel Poll Enable Register
is cleared at power-on.
E.g.
Sending "*PRE 8" sets bit 3 of the Parallel Poll Enable Register. This will cause the
Summary bit of the Questionable Status register (bit 3) in the Status Byte to generate
a TRUE ist message whenever it gets set.
Command: *PRE , *PRE?

Status Byte

The status byte query will return the contents of the status byte register and the MSS
(Master Summary Status) message. The response is in the format of a weighted
decimal value representing the status byte register and the MSS message (bit 6).
Thus, the response to *STB? is identical to the response to a serial poll except that
the MSS message appears in bit 5 in place of the RQS message. (See “Status Byte”
on page 155 for details.)
Command: *STB?
SCPI equivalent:
STATus:SBYTe[:EVENt]?
Power-on Status Clear

The Power-On Status Clear command controls the automatic power-on clearing of
the Service Request Enable Register, the Standard Event Status Enable Register, the
Parallel Poll Enable Register and the Error/Event Queue.
Command: *PSC {0|1}, *PSC?
SCPI equivalent for multichannel use:
SYSTem[]:POSClear {ON|OFF|0|1}
SYSTem[]:POSClear?
Individual Status Query

The individual status query allows the programmer to read the state of the IEEE
488.1 ist (individual status) message without performing a parallel poll. The query
returns a "1" or "0."
The ist message is formed by ANDing the bits in the Parallel Poll Enable Register
(*PRE) with the Status Byte and then ORing the result. In other words, the ist is
TRUE if any of bits of the Parallel Poll Enable Register AND'ed with the Status Byte
are TRUE.
Command: *IST?

The Operation Complete command causes the power supply to generate the
operation complete message in the Standard Event Status Register when all pending
operations have been finished.

Section 5. Current Sharing (6000 Watt only)
Overview
The current sharing function is only available for 6000 Watt units. Power supplies
can be equipped with the optional CANbus interface to allow current sharing
between units connected in parallel. Current sharing can use a maximum of 5
supplies. All power supplies must be the same model. Every unit must have a unique
address. See “Multichannel Operation (6000 Watt only)” on page 113.

Figure 5.1Connections for Current Share Operation

Theory of Power supplies may be connected in parallel to supply a large current to a load.
Operation Typically, because of differences in the load connections, each power supply may
provide different amounts of current to the load.
When multiple power supplies are configured for current sharing, the master supply
will make minute changes to the slave’s voltage and current to equalize the current
draw from each.
The slaves will track the master's voltage, current, output and output on/off setting.

Release 3.0

Current Sharing (6000 Watt only)
Overview

Configure Current sharing may be configured either by SCPI commands sent via a remote
Current interface or by using the Front Panel. The current sharing modes available are:
Share • No sharing
• Master: sets up the unit as the master controller.
• Slave: sets up the unit as the controlled slave.
Front Panel

In addition to selecting the current share mode, the master may be set up to display
the summed current from all units.
On the front panel, a MASTER or SLAVE annunciator will light up to indicate the
current share mode.

Sharing
Operation (6000 Watt only)” on page 113.)
Network
Configure one supply to operate as the master. Configure others to operate as
slaves.
2. Power down the units. Connect the CAN ports of all paralleled units as you
would for multichannel operation
3. Make load connections. It is recommended to keep load cables the same length
if possible. See Figure 5.1.
4. Power up the master, then all slaves.
5. Set the voltage on the master, then enable the output.

Current Sharing (6000 Watt only)
Operation

Operation
Once a current sharing network is setup, you may adjust the voltage setpoint on the
master. The master will automatically adjust the setpoints of the slave units to
equalize the current output of all units. You may also disable or enable the output of
the master, automatically disabling or enabling the output of all slaves.
You may use local or remote (RS-232, GPIB, multichannel or analog) control to
operate the master.
Slaves will be operating under remote control from the master and in local lockout.
Hence, they will only respond to remote queries or the OUT ON/OFF key on the
front panel.
The default display will show a greek letter sigma before the readback current if the
summed current output is being displayed. E.g. The display may read "60.00V Σ
500A". However, the setpoint displayed on the master is still the current limit for a
single unit.
The master or slave annunciators will light up to show that current share is operating
properly.
Power supplies may not enter calibration mode while current sharing, or enter
current share operation while in calibration mode.
Errors The slave annunciator will flash if it does not detect a master on the network. Check
the cable and the master configuration.
A master or slave will be disabled from current sharing (set to "No share") if:

•
•
•

there is more than one master connected to the CANbus, (Error +1811)
there are more than 4 slaves, (Error +1822), or
the model does not match that of the master, (Error +1822).

In each of these cases, the current share mode will be set to “No share”.
If a unit becomes disconnected due to a failure in communications, the master will
queue error +1812, "Current Share Slave Lost" and the slave will queue error +1821,
"Current Share Master Lost." The slave's output will be disabled, and the slave
annunciator will flash.
See “Current Share Error Codes” on page 222 for the list of error codes and
messages.

Appendix A. Calibration
These are the calibration procedures for the 6000 W unit. If you purchased a
12000 W unit, please reference the accompanying addendum for the correct
calibration procedures.

Overview
The calibration of the unit is software dependent; there are no potentiometers to
adjust.
Calibration may be performed via the front panel or SCPI commands. Front panel
calibration is partially automated. The calibration points are set automatically and
you will be prompted to enter the measurement data.
There are 10 items that need to be calibrated. Output voltage and output current are
mandatory. If you intend to use the analog programming interface, you must
calibrate it as well. It needs to be calibrated in both the 0-5V and the 0-10V ranges.
In each range, voltage programming, voltage readback, current programming and
current readback need to be calibrated.
All calibration data is taken at 10% and 90% of the rated outputs.
The setting and readback accuracy of the power supply should be checked annually,
and calibration done only if the unit is not operating within its specification.
Note POWER is calculated from voltage and current readback.

The OTP and AC off protection mechanisms are operational during calibration. All
other protection mechanisms are disabled.

CAUTION
Calibration procedures should only be performed by qualified users. Failure to
adhere to this warning may cause damage to the power supply, or pose a safety
hazard for the user.

Setup and Equipment

Setup and Equipment
• 6 digit DVM
• current shunt
• variable load
• 0-10 V DC power supply (analog programming interface)
• Load wiring sized for the maximum available output current. See Table 2.4, on
page 48.

To set up to calibrate output voltage and current:
Connect a load to the output of the power supply and a current shunt in series.
You will need to use the DVM to measure both the voltage at the output of the power
supply and the voltage across the shunt. You will need to convert the voltage across
the shunt to a current measurement.
To set up to calibrate the analog programming interface, you will need a 0-10V
power supply to provide a programming signal to the voltage and current
programming lines. You will also need to connect the DVM to measure the signal at
the readback lines.

Throughout these commands, the optional command [] is available
for the 6000 W units, but not available for 12000 W power supplies.
This manual shows SCPI commands in the following format:
CALibration:CURRent:LEVel {|MIN|MAX}

The command is expressed as a mixture of upper- and lowercase letters. The
uppercase letters suggest how the command can be abbreviated into a short form.
SCPI commands can be sent in long or short forms. The short form is better for data
entry. The long form is better for readability.
Command strings are not case sensitive: CURR, Curr, and curr are all acceptable
abbreviations for CURRent. As for the long form, CURRENT, Current, and current
are all acceptable.
The command strings include punctuation. While some punctuation is sent with the
string, other markings are used to identify different elements of the command syntax
and are not sent with the string.
The following punctuation is sent with the command string:

•
•
•
•

Colons (:) separate command keywords from lower-level keywords.
For example, CAL:CURR:STAT.
Blank spaces separate command keywords from parameter values.
For example, CURR 0.1.
Commas separate parameters from each other when more than one parameter is
sent in the same string. For example, CAL:STAT OFF,”1234.”
Semicolons (;) separate multiple commands from the same subsystem. This
allows for greater efficiency. For example:
CAL:CURR:LEV MIN;VOLT:LEV MIN

is the same as typing:
CAL:CURR:LEV MIN
CAL:VOLT:LEV MIN

•

Colons and semicolons can be used together to link commands from different
subsystems. For example:
CAL:CURR:LEV MIN;:MEAS:CURR?

The following punctuation is not sent with the command string:

•
•

Release 3.0

Braces ( { } ) identify a selection of choices. Choose one of the enclosed values.
Vertical bars, or pipes, ( | ) separate the choices found within the braces.

SCPI Command Reference
Using SCPI Commands

•

•

Angle brackets ( < > ) identify where specific values must be entered for a
parameter. For example, in the example at the top of the page, the parameter
 appears in the command string. To set the current setpoint to 0.1A, the
syntax is CAL:CURR:LEV 0.1.
Square brackets ( [ ] ) identify optional parameters. If an optional parameter is
not sent with the command string, a default parameter is sent in its place.

Using In the following example, Minimum and Maximum are offered as alternative choices
Minimum and to declaring a specific parameter value.
Maximum
CAL:CURRent:LEVel {|MIN|MAX}
The string CAL:CURR:LEV MIN sets the current calibration level to the minimum
model value.
Using A question mark lets you query the present value for most parameters. For example,
Queries to query the current calibration state use:
CAL:SEC:STAT?

You can also use the following to query minimum and maximum allowed values for
most parameters:
:VOLT? MIN
:VOLT? MAX
Note If you send 2 queries, it is best to read and respond to the first response before trying
to read the second. Otherwise, you may receive an incomplete first response followed by a
complete second response. To avoid this, you can either wait for and read the first response
before sending the second query, or send a device clear message before sending the
second query.

Terminating Every command string must end with a terminating  character. An
Characters IEEE-488 EOI (end-or-identify) can be used instead of a  character. It is
also acceptable to use a  followed by a . Terminating a
command string always resets the SCPI command path to the root level.
Common The IEEE-488.2 standard includes a set of common commands for functions such as
Commands reset and self-test. These common commands always start with an asterisk (*),
contain 4 or 5 characters, and may have one or more parameters. The command is
always separated from the parameter by a blank space. Multiple commands sent in
the same string are separated by a semi-colon (;). The following is an example of
how 3 common commands can be sent together in the same string:
*OPC; *PSC Off; *TRG

Parameter Types

Parameter Types
Several different data types are defined for use in program messages and response
messages.
Boolean Boolean parameters are single binary conditions such as 1 and 0, or ON and OFF.
Parameters The following is an example of a command that uses Boolean parameters:
SYST:COMM:GPIB:PONS {ON|OFF|1|0}

Discrete Discrete parameters are used when program settings have a limited number of
Parameters values. If you query a discrete parameter, the response will always be in the short
form with all uppercase letters. The following is an example of a command that uses
discrete parameters:
TRIG:SOUR {BUS|EXT|IMM|NONE}

Numeric Numeric parameters are number representations such as decimal points, optional
Parameters signs, and scientific notation. Values such as MINimum and MAXimum are
accepted as substitutes for numbers. When DEFault is provided as a parameter, the
machine selects the default value automatically. You can also use engineering unit
suffixes such as, V, A, or W with numeric parameters. In cases where specific
numeric values are accepted, the power unit will round the input parameters. The
following is an example of a command that uses numeric parameters:
VOLT:PROT {|MAX|MIN}

String String parameters are used when a series of ASCII characters is required. Strings
Parameters must be enclosed within single or double quotations. The beginning and ending
quotation marks must be matching. Quote delimiters may be included in the string
by typing the quotation marks twice without any characters in between. The
following is an example of a command that uses string parameters:
CAL:STAT ON, “0000”

Notes:
All legacy commands that change a value conform to the same rules as SCPI. Commands will cause an error if the unit’s remote
source, remote state, current share mode status and calibration status is incorrect.
Legacy commands do not have multichannel capabilities.
Query commands return a string containing the command itself.
The “CLR” command does not clear any legacy fault registers.
The “RST” command only clears the protections so that the voltage and setpoints can take effect. It does not change any setpoint
values. When a protection is tripped the unit’s output may be turned off (configurable).

Appendix C. Error Messages
Overview
Errors are placed in a queue as they are detected. The queue works on a first in, first
out (FIFO) basis. If the queue overflows, the last error in the queue is replaced with
error –350, “Queue Overflow”. When all errors have been read from the queue,
further error queries return 0, “No error”.
The error queue is cleared when any of the following occur (IEEE 488.2, section
11.4.3.4):

•
•

Upon receipt of a *CLS command
Upon reading the last item from the queue
All negative values are reserved by the SCPI standard. All errors unique to the power
supply have positive values.
