APC Automatic Transfer Switch redundant switch

APC rack Automatic Transfer Switches (rack ATS) provide reliable, redundant power to single-corded equipment. The rack ATS has dual input power cords supplying power to the connected load. If the primary power source becomes unavailable, the rack ATS will seamlessly source power from the secondary source without interrupting critical loads. Networked units have built-in network connectivity, which allows for remote management via web, SNMP, or telnet interfaces.
