APC AP8659NA3 – Rack PDU 20 A 208 V

Overview

APC AP8659NA3 is a zero‑U, metered‑by‑outlet rack power distribution unit (PDU) offering per‑outlet power measurement and remote switching control for rack‑mount environments. It is specified for IT infrastructure deployments where outlet‑level visibility and controlled power cycling are required to manage connected loads.

The PDU accepts a single‑phase input via a NEMA L6‑20P connector and supports up to 20 A nominal current with a fixed 208 V output. It provides 24 outlets: 21 IEC 60320 C13 and 3 IEC 60320 C19, enabling diverse device connectivity across server, networking, and storage equipment.

Designed for installation alongside standard 19″ rack rails without consuming usable U units, zero‑U mounting preserves space for active equipment. Its vertical profile suits high‑density cabinets and distributed racks where space efficiency is critical.

Integrated monitoring and control capabilities include web, SNMP, and Telnet interfaces for remote management of power states and metered current data. On‑device metering supports real‑time assessment of load distribution, and user‑defined thresholds assist in avoiding overload conditions.

In typical use, technicians deploy this PDU to sequence power to equipment during planned maintenance, validate rack load balancing capacity, or remotely recycle power to hung devices. Its zero‑U format is suited to dense rack environments where conserving vertical space is a priority.

This model is not intended for installations requiring 120 V output or configurations that demand multiple split circuits, as its design targets 208 V single‑phase power distributions common in data centers and colocation facilities.
