Eaton PDUMH20AT – 16‑Outlet 120 V ATS/Metered Rack PDU

Overview

The Eaton PDUMH20AT is a 1U automatic transfer switch (ATS) and metered power distribution unit (PDU) designed for rack‑mount deployment where redundant single‑phase power feeds must supply connected equipment with minimal interruption. IT and facilities engineers deploy it in core racks, IDF/MDF closets, and edge cabinets to maintain uptime during primary feed loss and to monitor aggregated load. The combined ATS and metered capability solves the need for both feed redundancy and local current measurement in a compact rack form factor.

Electrically, the PDUMH20AT supports 120 V single‑phase power with a 16 A continuous rating (≈1.9 kW) and features dual NEMA L5‑20P and 5‑20P input cords for primary and secondary feeds. It provides 16 NEMA 5‑15/20R outlets to distribute power to servers, switches, and peripheral devices. The metering function reports total output current on a front‑panel display to aid load verification and capacity planning.

Mechanically, the unit occupies 1U of vertical space in a 19‑inch EIA‑standard rack and includes rack mounting hardware for secure horizontal installation. Its all‑metal housing and integrated cord retention support structured rack environments with high cable density.

Integration into structured rack power ecosystems is straightforward with standard NEMA outlet types and industry‑common power feeds. The dual inputs allow connection to separate mains circuits or UPS outputs to maintain power continuity during maintenance or primary feed failure. Front‑panel visibility of current draw simplifies onsite assessment without remote management tools.

A typical deployment involves connecting redundant mains or UPS sources to the PDUMH20AT to feed rack‑level servers and network devices, ensuring continuity and visibility of load levels. This PDU is not suited for environments requiring per‑outlet switching or network‑based management; those needs are better served by switched or managed PDU variants with remote interfaces.
