APC Rack ATS 208V 20A 9 Outlets 1U Power Distribution Unit

Overview

The APC AP4434 is a rack automatic transfer switch designed to provide reliable redundant power distribution for servers, storage systems, and network equipment operating at 208 volts. It occupies just one rack unit, making efficient use of vertical space in crowded data center cabinets. With a 20 ampere IEC C20 input and a combination of eight IEC C13 outlets plus one IEC C19 outlet, it supports a variety of devices with different power requirements.

This unit automatically switches to a secondary power source within milliseconds if the primary feed fails, ensuring continuous operation without rebooting. A front panel display offers real-time current monitoring, while remote management options include web interface, SNMP, and Telnet, allowing administrators to monitor and control power distribution from anywhere on the network.

Connectivity and compatibility

The AP4434 connects to a single 208 V power source through an IEC C20 inlet and distributes power to a mix of IEC C13 and IEC C19 outlets. This setup supports a wide range of rack-mounted equipment, from standard servers to high-power devices, without requiring additional adapters or power strips. Remote management is accessible through standard network protocols including SNMP and Telnet, making it compatible with common data center monitoring tools.

Ideal uses and environments

This automatic transfer switch is well suited for small to medium data centers, colocation cages, edge computing racks, and test labs where maintaining continuous power is critical. Its compact size and remote management features make it a strong choice for environments where physical access is limited or where uptime is a top priority. The unit’s ability to handle mixed power loads and its quick transfer response help protect sensitive equipment and prevent costly downtime.
