Eaton PDUMNH20AT1 – 0U ATS Monitored Rack PDU 120V

Overview

The Eaton PDUMNH20AT1 is a 0U vertical automatic transfer switch (ATS) monitored rack PDU designed for environments requiring redundant power input with continuous load delivery. It is deployed by data center and network engineers to ensure uptime by automatically switching between primary and secondary AC sources when one input fails. This eliminates manual intervention and prevents downtime for critical rack equipment.

The unit operates within a 120 V single-phase power ecosystem and supports a 16 A continuous load (≈1.9 kW). It features dual input cords (NEMA L5-20P and 5-20P) for connection to separate power sources such as utility and UPS. Output distribution is provided via 10 NEMA 5-15/20R outlets, supporting mixed IT loads including switches, servers, and edge appliances.

The PDUMNH20AT1 is designed in a 0U vertical form factor, mounting along rack rails without consuming rack space. It is compatible with 19-inch EIA racks and includes mounting provisions for tool-less or bracket installation, enabling deployment in high-density cabinets, IDF closets, and colocation racks.

Integration is enhanced through remote monitoring capability, providing visibility into input status, load levels, and transfer events. The ATS functionality ensures seamless switching between power sources, while local indicators provide quick status verification. It integrates into rack power architectures alongside UPS systems to maintain redundancy at the rack level.

A typical deployment involves connecting dual power feeds (e.g., UPS + utility or dual UPS systems) to maintain continuous power for critical devices in a rack. This unit is not suitable for environments requiring per-outlet switching control or high-voltage (208/230 V) distribution, as it is designed for 120 V redundant input scenarios only.
