ATC-100 CONTROLLER

Select Units

Overview

The ATC-100 is a comprehensive and multifunctional microprocessor-based ATS controller. It is a compact and self-contained panel-mounted device that is designed to replace traditional relay and solid-state logic panels.The ATC 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. The ATC-100 monitors the condition of the three-phase line to line voltage and the frequency of both the utility and generator power sources. It can also be set up for single-phase operation. The ATC-100 provides the necessary intelligence to ensure that the transfer switch operates properly through a series of selectable sensing and timing functions.
