850 & 1700 Watt DC Programmable Power Supplies
Sorensen XG 850 & 1700 Series
Now, 1700W of Power in a 1U Power Supply
The Sorensen XG 850 & 1700 Series are industry leading programmable DC
power supplies designed for test, production, laboratory, OEM and quality
assurance applications. The newest member of the family, the XG 1700,
is a high power density 1700 Watt, 1U programmable power supply with
constant voltage and constant current modes, automatic cross-over and
numerous features enabling cost effective, easy system integration.
Easy System Integration
The Sorensen XG Series of system power supplies are designed for ease of
integration into automated test and other equipment.
Remote Serial Programming:
Digital programming is exible and easy, because in addition to precise,
digital encoder front panel control and simultaneous voltage and current
displays, the XG includes standard RS232/RS485 and USB remote control
interfaces. It also offers optional GPIB and LXI Class C Ethernet control
inputs. Commonly used, SCPI compliant, device drivers are available to
support system applications. To allow for fast programming and to unload
your system controller, DC voltage or current sequences can be programmed
into a specic memory location, using compliant SCPI commands. The XG
supports autonomous program sequencing with the capability to store,
recall and execute pre-programmed test routines including the operation of
the auxiliary outputs, minimizing command latency and system controller
overhead and thereby maximizing system throughput.
One example is to simulate the engine startup standard used in the
automotive industry. This unique Auto Sequence Programming functionality
is additionally powerful combined with the XG’s excellent slew-rate
specications.
Simple Multi-Channel Serial Control:
The XG Series, like most of the Sorensen DC power supplies, provides a
multi-channel control system. With this method, it is possible to congure
many power supplies into a one-master, multi-slave, single multi-channel
power-sub-system. One master can control up to 30 slave-units through a
simple cable (RS-485) using RJ-45 connectors.
This method of multi-channel control is much easier to manage from a
software programming point of view and provides much less complexity
from an interfacing and wiring point of view (one single GPIB or IP address
controlling multiple DC output channels).
Key Features
• Standard Digital Interfaces – USB & RS232/485
• Auxiliary 5V / 15V outputs
• LXI Ethernet and Isolated analog interfaces
• Power Factor Correction – PFC & universal AC input
• Sleep Mode – Auto “sleeps” after period of non-use (1700 only)
• Easy “cover on” soft calibration
• Programmable fold-back protection delay
Applications
•Burn-in •Compliance Testing
•Materials Research •Process Control
•Product Validation •Automotive Electronics
•Rack ATE Systems •Battery Charging
Output Auto Start Mode (Auto Restart)
The Auto Start mode establishes the state of the output of the power supply
after recovery from a complete power cycle (all front panel LEDs are not
illuminated), or after recovery from a PC failure or reboot. If Auto Start mode
is set to On, the power supply output will return to its previous value. Also,
after the loss of any remote digital control, the XG unit will remain active in
its last programmed setting and will not disrupt any test process.
Auxiliary Auto Start Mode
The Auxiliary Auto Start mode determines the state of the auxiliary output
after a complete power cycle (all front panel LEDS are not illuminated). With
Auxiliary Auto Start mode turned to On, the auxiliary output will be activated
after the power supply is powered up again.
Digital I/O Features with Analog Control
Most DC power supplies provide a 0 to 5 or 0 to 10 V analog control range
to control the DC output from zero to full DC output range. But what if these
analog control-signals are not exactly covering the range you need? XG
analog control and read-back full scale signals can be user dened, from 0
to 2V to 0 to 10V, facilitating easy substitution of the XG into existing test
or process control systems.. In fact, it’s just a push-of-a-button front-panel
exercise, to make the XG compatible with your analog control system.
Included Auxiliary Outputs
In many ATE systems one or more low power, xed voltage supplies are
needed to power accessories within the system. For this purpose, the XG
Series provides two auxiliary DC output channels, 5V / 15V each 0.4 Amps.
Both auxiliary power channels are switchable directly from the front-panel or
through SCPI commands. In this way, it is possible to drive output disconnect
or polarity reversal relays, without needing a complicated computer
controlled relay board, further reducing system cost and complexity.
Environmental Features
Variable Fan Speed Control: The XG’s innovative approach to fan speed is
determined by internal heat sink temperature. This allows the fans to adjust
to a constant optimal speed when the output of the supply is being pulsed,
which reduces audible noise and increases fan life.
Power Saving Standby Mode (1700 Only): When the XG 1700 has been in
an idle state, the supply can go into “sleep mode”, much like a computer
monitor. This will allow the user to save energy and minimize lab noise. Since
an XG 1700 left in sleep mode is still “on” the user will have quicker access
to an enabled output.
