AUTOMATIC TRANSFER SWITCH
Model ATS-30A
1 Introduction
This ATS-30A product is designed with two independent power inlets to supply power to the load from a prima-
ry power source. Should primary power source fail, the secondary will automatically back up the connected
equipment without any interruption. The transfer time from one line to another is seamless to the connected
equipment. After switching to a secondary power source, the ATS can also switch power back to the primary
input when power to the primary input is restored.
