Eaton PDUMH20AT – Metered ATS PDU, 16 Outlets

Product Overview

The Eaton PDUMH20AT is a horizontal 1U metered automatic transfer switch (ATS) PDU that gives single-corded network devices a redundant power option. Rated 120V at 20A, it distributes power through 16 NEMA 5-15/20R outlets from an L5-20P input, with dual input cords supporting connection to separate primary and secondary power sources. This metered ATS PDU is designed for server rooms and network closets that need automatic failover protection for equipment lacking a dual power supply, along with local current monitoring to track load.

Product Description

This 1U horizontal PDU combines automatic transfer switching with local current metering to provide redundant power protection for single-corded network devices. Dual input cords connect to separate primary and secondary power sources; if the primary becomes unstable or fails entirely, the ATS switches over to the secondary source until the primary is restored and stable, keeping connected equipment powered throughout. This redundancy works with any two compatible AC power sources, supporting configurations from a single UPS providing hot-swappable protection to fully redundant setups where each cord connects to a separate UPS system. In a two-UPS environment, Eaton recommends a full-time sine wave UPS with zero transfer time on the primary input cable. An on-board ATS processor continuously evaluates power quality on both input sources, preventing a transfer to the secondary source if it's unavailable or of lower quality than the primary — protecting connected equipment from switching to a worse power condition. Front-panel LEDs display which input source is currently active, giving technicians a quick visual status check. Sixteen NEMA 5-15/20R outlets accommodate both standard and 20A-rated equipment plugs, and the L5-20P input plug connects the unit to a 20A circuit. Local metering gives IT staff continuous visibility into output current, helping prevent overloads as equipment is added to the rack.

Key Features

• Automatic Transfer Switching — Dual inputs provide millisecond failover from a failed or unstable primary source to a secondary source.
• Local Current Metering — Continuous output current monitoring helps prevent overloads as equipment is added to the rack.
• 16 NEMA 5-15/20R Outlets — Accommodates both standard and 20A-rated equipment plugs on a single PDU.
• Power Quality Evaluation — An on-board processor prevents transfer to a secondary source that is unavailable or of lower quality than the primary.
• Front-Panel Source Indicator LEDs — Displays which input source is active for a quick visual status check.
• Horizontal 1U Form Factor — Fits standard EIA 19-inch racks without consuming excessive rack space.

Typical Applications

• Data center
• Server room
• Network closet

Frequently Asked Questions

What equipment benefits from this ATS PDU?

Single-corded network devices without a redundant power supply benefit most, since the ATS provides automatic failover between two independent power sources.

How fast does the transfer between sources happen?

The ATS switches to the secondary source within milliseconds if the primary becomes unstable or fails, helping avoid an interruption to connected equipment.

Do I need a UPS on both input cords?

A UPS is not strictly required on both, but Eaton recommends a full-time sine wave UPS with zero transfer time as the primary source when using two UPS units for maximum protection.

Does this PDU monitor load locally?

Yes, it provides local current metering so staff can monitor output load and help prevent circuit overloads.

What outlet types does this PDU support?

It includes 16 NEMA 5-15/20R outlets, accommodating both standard 15A and 20A-rated equipment plugs.

What warranty applies to the PDUMH20AT?

Eaton backs this unit with its standard manufacturer warranty; contact Creation Networks for the current term and any extended coverage options.

Can Creation Networks help plan a redundant power setup with this PDU?

Yes, our team can help you plan primary and secondary source connections for your specific redundancy needs.
