Product Features
Product Benefits
ASCO Series 300 and 7000 Power
Transfer Load Centers integrate the
most commonly specified components required to help protect
system loads from power outages,
sags, surges and over-current protection of load conductors.
Integrating components and
factory wiring them into one
enclosure significantly reduces
installation time, overall cost and
minimizes on site problems and
installation errors.
ASCO 7000 Series Power Transfer Load Center
with quick-connect Cam-Lok assembly
and Telco section
•Load Distribution or Load Center
that distributes 240/120 volt
single phase or 208/120V three
phase power to site equipment.
•Main and alternate source circuit
breakers that provide over-current protection and disconnect
for convenient and safe serviceability.
•Transient voltage surge suppression for normal and emergency
power sources.
•Optional ASCO Thin Web Server
for 24/7 remote connectivity
with a single site or a network of
sites spanning the country.

ASCO Series 300 Power Transfer Load Center
with quick-connect Cam-Lok assembly
and Telco section
•Optional Telco cabinet for customer mounting of telephone
equipment.
The shallow, space saving design
provides easy access and serviceability. The load center is service
entrance rated, listed to UL 67
and is available in a UL Type 1
(indoor) or UL Type 3R (outdoor)
enclosure.
When power fails, the automatic
transfer switch follows user-set
time delays to start the generator, transfer the load to the generator, reconnect to utility power
when it returns and shut down
the generator after generator
cool down. An automatic engine
exerciser tests the generator with
or without loads.
The load center also has a controls and status indicators panel.
Controls include a test, time delay bypass and engine exerciser
switches. LED’s indicate transfer
switch position and source availability status.

Project management you can depend
on for your mission-critical loads
Why Manage Multiple Components?
Multiple power-related cabinets and components consume valuable floor and wall space inside equipment
shelters at communications sites.
Integrating components into a single, space-saving
cabinet is the answer. The components operate as a
power transfer load center.
The area they demand, including mandated clearances, can total as much as 23 sq. feet for 200 or 400
Amp Services.
Benefits include reducing installation costs, time,
potential errors and improved reliability.
ASCO Power Technologies offers a comprehensive
family of power transfer load centers that can be
tailored to virtually any site.
With space at a premium and more advanced communications technologies being installed at sites, it
makes sense to streamline and simplify site power
protection and distribution strategies.

And when multiple components are located outside of
shelters, the potential for leaks and weather-induced
damage is that much greater.

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.

The module has two port connectors used for ATS &
Power Manager (accessory 85L) connectivity. The serial
connection is accomplished from a 5 – pin terminal
header/socket block. RS – 485 serial networks allow
for up to 32 modules to be set up in a daisy chain
configuration to connect to ASCO communication
systems.
The connectivity module is used to bring several different
serial devices that communicate at different baud rates
and then with different protocols to a common Ethernet
media. This module is used to connect the 300L/7000L
series PTLC, and ASCO Remote Annunciators to a
standard Ethernet TCP/IP network with standard 10BaseT
(RJ-45) connectors. The module has customized
