APC AP8461 5 7kW Metered by Outlet ZeroU Rack PDU

APC AP8461 Metered‑by‑Outlet Rack Power Distribution Unit 208V

Overview

The APC AP8461 is a metered‑by‑outlet rack power distribution unit (PDU) intended for structured AC power distribution and detailed energy monitoring in data center and enterprise rack environments. It is deployed by data center power engineers, facilities staff, and network administrators to distribute 208 V utility power to multiple connected devices while providing per‑outlet metering for granular visibility into power usage per device. This device does not provide UPS backup or surge suppression; its core function is real‑time power distribution and monitoring.

This model supports 208 V AC input at up to 20 A via a NEMA L21‑20P plug, delivering approximately 5.7 kW (5700 VA) of total load capacity. Power is distributed through 24 total outlets — 21 IEC 60320 C13 and 3 IEC 60320 C19 — enabling a broad range of servers, switches, storage, and other IT devices to be powered from a single branch feed.

The AP8461 installs in a zero‑U vertical rackmount configuration, allowing mounting along the side rails of 19‑inch racks or enclosures without consuming horizontal rack units needed for active equipment. This design conserves usable rack space while providing high outlet density.

Integrated load metering provides local and remote visibility into current, voltage, active power, and energy usage. Remote access is supported via standard network interfaces including Web, SNMP, and Telnet, enabling integration with centralized infrastructure management systems and proactive alerting based on user‑defined thresholds.

Typical deployments include high‑density server cabinets, network core racks, and colocation facilities where distributed equipment requires detailed monitoring for load balancing, capacity planning, and energy‑aware operations. This PDU is not intended for single‑phase 120 V environments or as a UPS replacement.
