The APC NetShelter Rack Automatic Transfer Switch (ATS) AP4424A is a 2U rack-mounted device engineered to deliver high-availability redundant power for single-corded IT equipment within racks. Designed by APC by Schneider Electric, this ATS supports dual 32A IEC 309 (IEC 60309) inputs and distributes seamless power to 16 IEC C13 and 2 IEC C19 output outlets rated at 230 V single-phase with a load capacity of approximately 7400 VA.

Featuring transfer times under 10 ms, the AP4424A ensures uninterrupted operation by instantly switching power sources upon any interruption of the primary input. Integrated circuit breaker protection guards against overcurrent situations, while a local LCD status display provides real-time insights into source status and load conditions.

This unit supports comprehensive network management through a secure Web UI, SNMP, and CLI interfaces, and includes a field-replaceable Network Management Card (NMC) for enhanced functionality. It is fully compatible with the EcoStruxure IT platform, enabling centralized monitoring and remote configuration.

The product operates reliably across a broad temperature range (-5 to 45 °C), humidity levels (5–95% non-condensing), and altitudes up to 10,000 ft (3,048 m). Included with the ATS are dual 2.44 m power cords, rack mounting hardware, and brackets designed for a 2U rack installation. It meets rigorous EMI/EMC standards such as EN 55022 Class A and FCC Part 15 Class A, ensuring compliance and minimal interference.

Ideal for mission-critical IT environments including data centers, network closets, and edge computing racks, the AP4424A is a robust solution for maintaining power continuity and protecting sensitive equipment against unexpected outages.
