As we become more depen-

dent on the quality and

reliability of electrical power,

interruption or complete loss

of power can create serious

and even crippling financial

losses, or impose dangers to

life and safety.

ASCO Power Technologies

(ASCO) provides the solu-

tions to handle the transfer

of critical loads to emer-

gency sources reliably and

with state of the art prod-

ucts. Using ASCO products

can mean the difference

between a minor inconve-

nience and a major catastro-

phe. You’ll find ASCO Power

Transfer Switches wherever

there is a critical load to be

protected.

When flexibility in power

switching is a must, ASCO

offers a variety of product

solutions to meet virtually

every application require-

ment, including distributed

generation applications.

That’s why the 7000 SerieS

is available in open, delayed,

closed and closed soft load

configurations. Additionally,

switched or overlapping

neutral options provide for

reliable operation of ground

fault protection systems and

reduction of voltage tran-

sients from unbalanced load

switching.

ASCO Power Transfer

Switches are the first CE

Marked, IEC 60947-6-1

compliant Transfer Switches

in the world.

nate sources of power, regardless of ampacity size, is

achieved by a reliable, field proven solenoid operating

mechanism. When combined with a programmable

microprocessor controller with keypad and LCD display,

they offer the most advanced method of transferring

all types of loads, such as motors, electronic drives,

UPS’s and microprocessor based systems. 7000 SerieS

Power Transfer Switches are available open or enclosed,

rated 1600 Amperes (shown with optional front

connected terminals and Power Manager).

Delayed Transition Transfer Switching

Fig. 3: Four pole, Delayed Transition

Transfer Switch rated 2000 Amperes.

ASCO Delayed Transition Transfer Switches are designed

to provide transfer of loads between power sources with a

timed load disconnect position for an adjustable period of

time. Applications include older style variable frequency

drives, rectifier banks, and load management applications.

• Available in 150 through 4000 Amperes.

• Utilizes reliable, field proven solenoid operating

mechanisms.

• Mechanical interlocks to prevent direct connection

of both sources.

• Indicator light (16mm, industrial grade

type LED) for load disconnect position.

• Adjustable time delay for load disconnect position.

Closed Transition Transfer Switching

ASCO Automatic Closed Transition Transfer Switches feature

main contacts that overlap, permitting the transfer of electrical

loads without power interruption. The switch transfers in a

make-before-break mode if both sources are within acceptable

parameters. Control logic continuously monitors source

conditions and automatically determines whether the load

transfer should be open (conventional non-overlap mode) or

closed transition. Available 150 through 4000 Amperes.

Closed Transition Transfer within 5 electrical degrees is achieved

passively, without control of engine generator set. Therefore,

no additional control wire runs are required between the ATS and

engine generator set governor. Plus, protective relaying may

not be required under normal operation since the contact over-

lap time is less than 100 milliseconds (consult your local utility

on protective relay requirements).

Failure to synchronize indication and extended parallel time

protection is built-in to all 7000 SerieS closed transition

controls to prevent abnormal operation.

The 7000 SerieS Microprocessor Based Controller is used with all sizes of Power

Transfer Switches from 30 through 4000 Amperes. It represents the most advanced

digital controller in the industry and includes, as standard, all of the voltage,

frequency, control, timing and diagnostic functions required for most emergency

and standby power applications.

Because of severe voltage transients frequently encountered with industrial

distribution systems, the microprocessor logic board is separated and isolated from

the power board as shown below. This improves electrical noise immunity perfor-

mance and helps assure compliance with the rigorous transient suppression stan-

dards highlighted below.

The 7000 SerieS microprocessor controller is a Power Control Center which

allows the user to easily access detailed information on: system status; power

source parameters; voltage, frequency and time delay settings; optional

feature settings; historical event log; and system diagnostics. A four line,

(20) character LCD has a backlit display which enables easy viewing under all

conditions. The user can navigate through all screens using only six buttons,

which also allows selection of: (18) different source parameter settings; (16)

standard time delays; (12) standard feature settings; up to seven independent

engine exercise routines; and even the language (English, German, Spanish,

French, etc.) which appears on the display.

Since the Power Control Center must be visible and operable through

the enclosure door, it has been qualified for use in industrial and outdoor

applications. This includes installation in Type 3R (outdoor/rainproof),

ASCO 5200 series Metering

Power Manager

The ASCO 5200 SerieS Power Meters are microprocessor

based metering devices that provides real-time measure-

ment of single and three phase power systems. The 5200

SerieS uses digital signal processing technology to measure

voltage and current per phase; real, reactive and apparent

power, and bi-directional energy. All measurements can be

viewed locally with a backlit liquid crystal display and/or

displayed remotely with ASCO POWERQUEST ® products.

Direct voltage input for systems up to 600 Volts AC

can be monitored without the use of external potential

transformers (PTs). Measures three phase currents and a

fourth current input is available for measuring current

in the neutral conductor. The 5200 SerieS includes one

discrete input for transfer switch position.

Note: The ASCO Power Manager is also available as a separate unit for monitoring electrical parameters anywhere in the power distribution system.
