Protect single-rack and edge infrastructure from upstream power loss with automatic source transfer in a compact 1U footprint. The APC NetShelter Rack ATS AP4423A is built for environments that need continuous power from two independent feeds, with automatic switching to keep connected equipment running when the preferred source fails. Rated for 16 A at 230 V and designed for 50/60 Hz operation, this rack ATS supports practical deployment in mixed enterprise and colocation environments. Dual C20 inputs provide source redundancy, while the outlet mix of 8 C13 and 1 C19 supports a range of IT devices without adding external power strips or adapters. The rack-mount form factor keeps cabling contained and preserves valuable rack space. For teams that cannot afford avoidable downtime, this ATS adds a clear layer of resilience at the power entry point. It is a straightforward choice when you need automatic transfer, rack-friendly installation, and the outlet density to support real-world server, network, and storage loads.
