Liebert RDC Remote Distribution Cabinet
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 easy 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 labeled.
