RPR 60KVA PowerBay
Modular Redundant Power Router
Cabinet System
Redundant -48VDC A/B Input power router system for reliable uninterrupted powering of single input
DC power equipment such as DC-AC inverter systems.
Compact footprint: 7' tall x 24"W x 30"D cabinet. Scalable and modular.
Single, Dual or Triple bus configurations for flexible DC source input routing.
CSI RPR300 high density redundant power router modules. Hot-swap capable with individual output
circuit breakers to feed inverter module inputs. 60KVA Bay accepts six RPR300 modules for 1,800A
cabinet DC routing ampacity.
Integrated supervisory controllers provide voltage, current, thermal status, breaker trip alarm and other
status data.
Proven 10 year high reliability RPR product history - units installed in many communications facilities.
High power density solution to feed new generation 3-Phase DC-AC Telecom inverters from redundant
A/B DC power plants.
Application notes:
DIAGRAM
Power from redundant and isolated "A" and "B" -48VDC power plants is fed to the RPR (Redundant
Power Router) module input. Internal low loss "steering diodes" provide power combining without risk
of backfeed from one DC plant to the other. There is no transfer interruption in load support from one
plant or the other providing the power through the routing circuit. Normal operation features an
approximate 50% load share from both DC plants assuming the input voltage to the RPR system is equal.
Entire inverter load can be supplied from only one DC plant or the other during maintenance or
emergency shutdown of the opposing DC plant. RPR modules are fed from A/B inputs and provide circuit
breaker protected "C-bus" redundant fed outputs to feed to the DC-AC inverter module inputs.
