Eaton EMI318‑10 – Metered 3‑Phase Rack PDU 5.76 kW 39 Outlets

Overview :

The Eaton EMI318‑10 is a metered rack‑mount power distribution unit (PDU) designed to deliver conditioned three‑phase AC power to server, network, and storage equipment in data center and electrical infrastructure environments. It is deployed by data center engineers, IT operations teams, and facilities technicians to distribute power while monitoring load characteristics locally or over a network. As part of Eaton’s ePDU G3 series, it provides metered input measurement for visibility into current, voltage, power, and energy usage at the distribution layer.

From a deployment perspective, this PDU supports 16 A three‑phase input through a NEMA L21‑20P plug, delivering up to 5.76 kW of power across a mix of AC receptacles tailored for rack equipment. The configuration includes 30 IEC C13, 6 IEC C19, and 3 NEMA 5‑20R outlets. Its metered design includes a local display and remote monitoring capability via Ethernet and RS‑232 interfaces, enabling power consumption tracking and capacity planning.

Typical deployments for the EMI318‑10 include 38U or larger server racks, telecommunications closets, and network operations centers where three‑phase power is available and centralized load monitoring is required. The vertical 0U form factor attaches to the rack rail, preserving valuable rack units for active equipment. It supports 50/60 Hz electrical ecosystems.

Integration with infrastructure management platforms allows the PDU to communicate real‑time electrical measurements and alarms to management software. Local LCD metering displays input and output metrics for on‑site diagnostics. Its plug and receptacle combinations accommodate mixed equipment types—servers, storage, networking, and peripherals—without additional adaptors or distribution panels.

In a practical deployment scenario, operators use the EMI318‑10 to balance loads in dense rack environments and ensure that power capacity is not exceeded. Monitoring data feeds back into capacity planning tools, helping optimize equipment placement and power provisioning. It also assists with billing grade energy usage reporting in colocation environments where power cost allocation is required.

This PDU should not be used where switched outlet control or outlet‑level metering is required; it provides input metering only. It also is not suitable for AC redundancy topologies requiring dual power feeds per load without additional PDUs or infrastructure.
