APC AP4422 Rack ATS 230V 16A IEC 309 | Rack PDU, Enterprise

APC AP4422 brings automatic transfer capability to rack environments that need redundancy without unnecessary complexity. Designed for 230 V systems with 16 A input capacity, it switches connected loads between two IEC 309 input sources and delivers power through an IEC 309 output connection. That makes it a practical fit for racks where continuity matters, but space and power budgets are tighter than in larger data center deployments. For IT teams, the value is straightforward: fewer manual recovery steps, less exposure to single-feed failures, and a cleaner way to support critical equipment in branch offices, network closets, and edge cabinets. The ATS function helps keep essential devices online when one source is interrupted, which can reduce service disruption and support more predictable operations. Compared with basic power strips or single-feed distribution, AP4422 adds a layer of resilience that is worth the premium in environments where downtime has a real cost. It is a focused power component for teams that want APC reliability and source-transfer behavior in a compact rack power solution.
