APC Rack ATS AP4421A 230V 1U 10A C14 In 12 C13 Out | Rack Mount

Protect single-corded rack equipment from upstream power interruptions with automatic source transfer in a compact 1U footprint. The APC Rack ATS 230V 1U is built to maintain power continuity when the preferred feed is lost, helping keep servers, network gear, and other critical loads running through transfer events. With a C14 input and 12 C13 outlets, this unit is suited to dense rack environments where space is limited and uptime matters. The 10 A, 230 V design supports practical deployment in international infrastructure standards, while the automatic transfer function reduces the need for manual intervention during power source changes. For teams that need more than a basic PDU, Rack ATS adds a layer of resilience that justifies its place in higher-value racks. It helps reduce service disruption risk, supports cleaner power architecture, and gives operations teams a more controlled path for maintaining availability across redundant feeds. In environments where downtime is expensive, that difference matters.
