ATC-100 Controller
Product Description
The ATC-100 Controller is a
comprehensive, multifunction,
microprocessor-based ATS
controller. It is a compact,
self-contained, panel-
mounted device designed to
replace traditional relay and
solid-state logic panels.
Application Description
The ATC-100 Controller
provides both fixed and
jumper-selectable settings
to allow for a range of
applications. It operates from
all system voltages between
120 and 480 Vac, single-
phase and three-phase, at 50
or 60 Hz. In addition, a period
of no control power operation
is provided. The ATC-100
Controller monitors the
condition of the three-phase
line-to-line voltage and
frequency of both the
utility and generator power
sources. It can also be set
up for single-phase operation.
The ATC-100 controller
provides the necessary
intelligence to ensure that
the transfer switch operates
properly through a series of
sensing and timing functions.
The ATC-100 controller
can be used with both the
breaker-based design and
the contactor-based design.
See Page 75 for ranges and
factory settings.
