Eaton PDUMH20‑ISO 1U 120 V 16 A Metered PDU with ISOBAR Surge
Overview :
The Eaton PDUMH20‑ISO is a horizontal rack mount power distribution unit (PDU) that combines local load metering with built‑in AC surge and noise suppression. It is deployed by data center infrastructure engineers and network facilities teams in server rooms, branch racks, and IDF/MDF closets where real‑time visual load feedback and transient protection are needed without network management capability. The unit delivers consolidated distribution and protection to connected IT equipment from a single 20 A feed.
Electrically, this PDU accepts single‑phase 100–127 V (nominal 120 V) AC input via a NEMA L5‑20P plug with 5‑20P adapter on a 15 ft (4.57 m) cord. It is rated for 20 A (agency de‑rated to 16 A continuous), providing approximately 1.9 kW at 120 V capacity distributed to (12) NEMA 5‑20R and (2) NEMA 5‑15R receptacles. A front‑panel digital current meter displays total output current in amps for on‑site load monitoring.
Mechanically, the PDUMH20‑ISO occupies 1U (EIA‑310) horizontal rack space and installs with included rackmount hardware. Its reversible housing supports installation facing front or rear, and accessories allow wall or under‑counter mounting. The compact depth supports racks with space constraints.
Integration is limited to local features — this model does not include network connectivity, remote control, or DCIM interfaces. The standout addition is ISOBAR surge suppression with 3,840 joules rating and diagnostic LEDs that indicate protection status and wiring faults, enhancing resilience against transient AC events.
Typical deployments include small to medium IT racks powering servers, switches, storage, and auxiliary gear where both local current awareness and surge suppression are needed without network management. This unit is not appropriate for environments requiring networked PDU control, per‑outlet metering, or switched outlets — networked or switched PDU models should be selected instead.
