One power feed drops and your whole rack goes dark. That's the 2am phone call nobody wants. The AP4422A sits in a single U of your NetShelter rack, takes two IEC 309 feeds, and hands one redundant output to your single-corded gear. Feed A fails? It transfers to Feed B automatically. No manual switching. No downtime window. Fifth-generation design with APC NMC3 gives you network port sharing, environmental monitoring, and enhanced security out of the box. Rated at 16A, 230V single-phase, 3840VA — enough headroom for a full rack of servers or networking gear without breaking a sweat
