ᓼ
The Recognized Leader in Power Transfer Switch Technology
Offers the Most Advanced Transfer Switches in the World.
7000 SERIES
ASCO Power Transfer Switches are the standard of the
industry. High speed transfer of loads between alternate 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, UPSs
and microprocessor based systems. 7000 SERIES Power
Transfer Switches are available open or enclosed, in
ampacity sizes from 30 through 4000 amperes with the
largest selection of optional accessories offered anywhere. All switching configurations are available with an
integrally mounted bypass-isolation switch and/or rated
for use in service entrance applications.

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 overlap 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.
Fig. 2: Four pole, Closed Transition Transfer Switch
rated 1000 amperes in Type 1 enclosure.
Delayed Transition Transfer Switching
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 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.

7000 SERIES Microprocessor Controller
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 performance and helps assure compliance with the rigorous transient suppression standards
highlighted below.

Power Manager
The ASCO 5200 SERIES Power Manager is a microprocessor
based metering device that provides real-time measurements of single and three phase power systems. The
Power Manager 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 ® or SiteWeb® 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 Power Manager includes
one discrete input for transfer switch position, eight
general purpose discrete inputs, and four relay outputs
for monitoring and controlling external devices.
