CyberPower PDU33105 PDU 3-Phase 120-208V 30A 44 Outlets NEMA L21-30P 0U LCD

3-Phase Monitored PDU for Data Centre Racks

The CyberPower PDU33105 distributes 120V and 208V three-phase power at 30A through a NEMA L21-30P inlet. Forty-four outlets include two NEMA 5-20R, thirty-six IEC-320 C13 and six IEC-320 C19 receptacles. The 0U vertical form factor mounts in standard racks without consuming rack units. Built-in LCD metering and network alerts via email, SMS text and SNMP trap give administrators real-time visibility.

Sustained Load Behaviour on Three-Phase Circuits

The unit is derated to 24A continuous current in accordance with electrical codes for 30A branch circuits. Three-phase distribution balances the load across phases, reducing neutral current and keeping each phase within the 24A limit during extended operation. Monitoring reports per-phase amperage so operators can redistribute equipment before a breaker trips. No internal over-current protection is listed; the PDU relies on upstream branch-circuit breakers.

Thermals, Noise and Power Draw in Normal Use

Passive power distribution generates negligible heat and produces no audible noise because there are no fans or active cooling components. The LCD display draws minimal power while providing voltage, amperage and kilowatt readings at a glance. A ten-foot input cord allows flexible placement within the rack row. The unit operates at 50Hz or 60Hz without derating.
