Liebert Remote Distribution Cabinet (RDC)

The Better Way To Wire High Density Facilities

The influx of client/server rack equipment is changing the content of data centers. There are more devices than before—and they consume less power than their predecessors. As a result, most power distribution units (PDUs) run out of circuit breaker poles before they run out of rated capacity.

The Liebert Remote Distribution Cabinet (RDC) extends the functionality of the PDU by packaging 168 poles (four complete 42-pole inline panelboards) in a stand-alone cabinet.

Unlike standard Liebert Precision Power Centers (PPCs), the RDC has no internal isolation transformer and requires 4-wire-plus-ground input from a PPC or other transformer. By separating the PPC transformer from the panelboard function, Liebert was able to create an extremely compact package that fits the area of a standard 24” x 24” raised-floor tile.

The individual panelboards inside the Liebert Remote Distribution Cabinet can receive power from different sources. This enables the RDC to provide fault-tolerant, fully maintainable dual-bus power to nearby load equipment. A dual-input RDC can be configured with two panelboards on each side sharing common input terminals.

Other Features Of The Liebert RDC:

Unobstructed wiring access for ease of installation

Complete isolation and maintainability

Optional clear door insert panels enabling visual inspection of the breakers without unlocking the cabinet

Optional adjustable accent panels to make it easier to compensate for breaker “creep”

Single, dual or four-input configurations

Optional current monitoring panel

Optional input junction box and underfloor conduit box UL and CE compliant and labeled

Conduit-landing plate, above, is positioned for easy cable access. Underfloor junction, inset, above right, is standard for 4-input models and optional for others.
