Automatic Transfer Switch

Overview

The American Power Conversion (APC®) Automatic Transfer Switch (ATS) provides redundant power to rack-mount equipment, ensuring high availability. The ATS supplies power from a primary input line; if that line becomes unavailable for any reason, the switch automatically begins supplying power from a secondary input line.
