Automatic Transfer Switch for Rack Power

This APC AP4423A provides automatic power switching for rack-mounted equipment. It accepts a single-phase input between 207 and 253 V and supports up to 3700 VA. The unit occupies 1U of rack space and includes nine output connectors with a 2.44 m input cord. Management is available through USB and Ethernet 10/100/1000 interfaces.

Suited for Single-Source Redundancy Needs

This switch protects servers and network gear that lack dual power supplies by transferring load to a secondary source during an outage. It is not intended for three-phase installations or environments requiring input voltages outside the 207 to 253 V range. Buyers needing higher capacity or different phase configurations should consider alternative power distribution units.
