Figure 1 at left shows the two most-
common uses of the RDC, in the
middle or at the end of a section of
equipment racks.
Figure 2 shows a simplified diagram
of how the RDC can be applied with a
single AC input per cabinet. Two PDU
transformers feed a Static Transfer
Switch, which in turn feeds two RDCs.
Figure 3 shows three RDCs, each
receiving feeds from two Static
Transfer Switches (STSs). Each STS is
fed by two PDU transformers, which in
turn are powered by two different
UPSs.
