APC APDU10452SM 208 V 3‑Phase Switched Rack PDU
Overview
The APC APDU10452SM is an advanced switched and metered rack power distribution unit (PDU) designed for dense enterprise and data center rack deployments requiring remote outlet control and comprehensive load visibility. Power teams and infrastructure engineers deploy this PDU when fine‑grained control of rack equipment power states and detailed energy monitoring are essential for operational efficiency and fault isolation. Its switched architecture enables individual outlet on/off control and sequencing from a remote interface while providing metering accuracy suitable for capacity planning and threshold alerting.
Configured for 208 V AC three‑phase input with a 60 A feed, the APDU10452SM supports up to 17.3 kW (17,300 VA) of load capacity across a high‑density configuration of 42 outlets. The units use an alternating phase design that groups outlets by phase to balance loads and simplify cord management in three‑phase racks. A vertical zero‑U form factor installs alongside rack posts without consuming usable rack units, maximizing space for active equipment in server rooms, colocation facilities, and enterprise cabinets.
The PDU supports dual Ethernet ports (Gigabit + 10/100) that enable network management card (NMC) connectivity, cascading PDUs, or network redundancy. An interactive LCD provides local power and metering readouts, and remote management over SNMP/Redfish/Web allows administrators to monitor real‑time voltage, current, power, and energy consumption. Hot‑swappable NMC support minimizes maintenance impact, and environmental sensor ports allow expanded monitoring capacity.
This device does not provide uninterruptible power or battery backup; continuity through power outages must be provided by upstream UPS systems. The APDU10452SM is optimized for racks with high‑density servers, storage, networking, and security equipment where controlled power cycling and metered load visibility improve uptime and operational workflows.
