The CPX requires –48 VDC plant battery power through two
separate lines for –48V power and battery return (A and B). The
power supply input voltage range is –40 V to –72 VDC, 13A
maximum configured system (balanced between the two power
supplies).
For external circuits, protect each branch with the appropriate-
sized fuse or circuit breaker (
13A slow-blow). Maximum surge
during power-up is 40A for 4 ms to the shelf (20A to each supply).
Rack
