APC by Schneider Electric AP4434A Rackmount Automatic Transfer Switch

Overview

The APC AP4434A is a 1U rackmount automatic transfer switch (ATS) designed to provide redundant power to critical IT infrastructure. It accepts dual power inputs from separate power distribution units or utility feeds, automatically switching to the secondary source if the primary fails. This ensures continuous operation for servers, network devices, and other sensitive equipment in data centers and network closets. The AP4434A model features two C20 input connectors and eight C13 output connectors, supporting a 20A input current at 208V.

Compatibility

This ATS is designed for integration into standard 19-inch rack systems. It is compatible with IT equipment requiring dual power supplies and a 20A, 208V power feed. It functions as a power distribution unit with automatic failover capabilities, suitable for use with servers, network switches, storage arrays, and other rack-mounted IT hardware that requires high availability. It is not tied to specific server models but rather to the power input requirements of the connected equipment and the power source infrastructure.

Installation Notes

The unit operates within an input voltage range of 187V to 228V AC and a frequency of 50/60 Hz. It requires a 20A input current and delivers 20A output at 208V. Operating temperature is specified from -5°C to 45°C, with storage temperatures ranging from -25°C to 65°C. Relative humidity can range from 5% to 95% during operation and storage. The device is UL ECOLOGO certified, indicating compliance with sustainability standards.
