Liebert cPDU Overview

Packaged Power Distribution for Critical Electronic Loads

Liebert cPDU is a compact packaged power-distribution solution that brings electrical distribution, computer-grade grounding, monitoring and alarm annunciation together inside one self-contained cabinet.

The product is available in 20kVA, 40kVA, 60kVA and 80kVA ratings for three-phase power-distribution requirements. It can provide three-phase or single-phase output arrangements according to the selected configuration.

A single-point grounding architecture creates a defined electrical reference for sensitive computer and communication equipment. The system is designed to support the non-linear loads commonly produced by modern electronic devices.

The individually protected 160A panelboard uses DIN-rail-mounted breakers and flexible outgoing cables. This enables distribution circuits to be arranged around the requirements of the connected critical equipment.

Built-in metering monitors electrical information at the main input and individual branch circuits. Available parameters include voltage, current, apparent power, active power, power factor, load percentage, energy and frequency.

Alarm annunciation helps identify overload, overcurrent, low-current, frequency and phase-related conditions. Modbus communication supports integration with compatible third-party monitoring platforms.

The pre-packaged and factory-tested cabinet uses one building-power connection, helping simplify the electrical connection while conserving valuable computer-room floor space.
