CyberPower PDU33103 PDU 3-Phase 120/208V 20A 44 Outlets NEMA L21-20P 0U LCD

Three-Phase Monitored PDU

The CyberPower PDU33103 is a three-phase monitored power distribution unit built for data-centre racks and server rooms. It accepts a 120/208 VAC 20 A feed through a NEMA L21-20P plug and distributes it across 44 outlets in a 0U vertical form factor. An integrated LCD provides local metering while email, SMS text and SNMP trap notifications alert administrators to power events. This unit suits operators who need per-outlet awareness on a three-phase circuit.

Derated 16 A Input and Outlet Mix

The 20 A input is derated to 16 A continuous per electrical code, so total connected load must stay within that limit. The outlet array comprises two NEMA 5-20R, thirty-six IEC-320 C13 and six IEC-320 C19 receptacles, giving a fixed mix of North American and IEC connectors. The 10 ft input cord sets the maximum reach from the branch circuit. Builds requiring a different plug type, single-phase supply or a higher continuous ampacity cannot use this PDU.

Forty-Four Outlets with C13 and C19 Headroom

With thirty-six C13 and six C19 outlets the PDU comfortably powers dense 1U and 2U servers, network switches and storage arrays that use standard IEC cords. The two 5-20R outlets handle occasional North American plug devices without adapters. Once all forty-four outlets are populated or the 16 A derated limit is reached, no further devices can be added. Racks needing more than six high-current C19 connections or a different outlet ratio will require an additional distribution unit.
