branch circuit emergency transfer switch for dimmable lighting loads

Series Downloads

Overview

The SWX-EPC-D-F-ATS is the one of the only UL1008 listed device for branch circuit emergency lighting control.

The SWX-EPC-D-F-ATS can be used with any dimming system (line voltage or 0-10V) and ensures that during a power interruption emergency lights will illuminate at full brightness. A triple safety design including time delay, mechanical, and electrical interlocks prevents inadvertent cross-connection, even in the event of device failure. The attractive universal mount package allows the device to be installed flush or surface in the space, or remotely. Complies with latest NEC requires and unparalleled in functionality and reliability.

Basic Operation

The Model SWX-EPC-D-F-ATS is a single zone, silent emergency transfer control with universal dimming capability. It can be used with line voltage dimming systems, as well as 0-10V. The SWX-EPC-D-F-ATS allows emergency lighting to be dimmed with regular lighting during normal times. In the event of a utility power interruption, the SWX-EPC-D-F-ATS will automatically transfer designated emergency fixtures from the dimming control to the emergency power source and bring them to full brightness, regardless of whether the dimming system is in operation or turned off.

Applications of the SWX-EPC-D-F-ATS include designated dimmable emergency luminaires in public places such as auditoriums, restaurants, conference rooms, theaters, and classrooms.
