1. Introduction

This ATS product is designed with two independent power inlets to supply power to the load from
a primary 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.
