Overview

The APC by Schneider Electric Rack Automatic Transfer Switch (ATS) provides reliable, redundant
power to single-corded equipment loads, such as servers. The Rack ATS has two input power cords
supplying power to the connected loads. If the primary source becomes unavailable or out of the
selected range, the Rack ATS will seamlessly source power from the secondary source without
interrupting critical loads.

The Rack ATS has built-in network connectivity, which allows for remote management via Web,
Telnet, SNMP, SSH or StruxureWare Data Center Expert

Inlets: The two (2) C20 inlets support the connection of two power cords (not provided) to link the
ATS to two separate power sources (A, B). The switch draws power from the preferred source and
automatically switches to the secondary source when necessary.

Outlets: The outlets connect the ATS to equipment in the rack or enclosure, providing a redundant
source of power to the connected equipment. The switch has eight (8) C13 outlets and one (1) C19
outlet.
