The APC NetShelter Rack Automatic Transfer Switch (AP4421A) is a high-reliability 1U rack-mounted device designed for seamless power redundancy in single-phase 230 V IT environments. With dual IEC C14 10A inputs and twelve IEC C13 10A outputs, it efficiently distributes power to multiple single-corded devices within a rack.

Built for minimal downtime, it features a rapid transfer time of approximately 10 ms, ensuring continuous power supply without disruption. Integrated Network Management Card (NMC/NMC3) allows secure remote monitoring and control via web UI, SNMP, and CLI protocols, and supports compatibility with APC's EcoStruxure IT platform for enhanced infrastructure management.

The unit includes visual indicators for AC input status and source supply, allowing quick onsite diagnosis even without network access. It supports environmental sensor integration for comprehensive rack monitoring.

Designed specifically for rack installation, the AP4421A occupies 1U space and comes complete with mounting hardware and brackets. Operating within temperatures from -5°C to 45°C and relative humidity up to 95%, it is well suited for demanding data center and edge computing environments.
