Specification Value
Voltage
Nominal input voltage -48 or 48 VDC
Maximum input voltage 75 VDC
Operating voltage range 36 to 72 VDC
Ripple/Noise 100 mV PARD*
Overshoot Must remain within regulation limits during startup or shutdown
Current
Max steady state input current 13.2 A
In-rush current 70 A
Input over-current Customer must provide fusing for facility DC feeds that protect the
system from catastrophic over-current within 20 uS. Fuse should
sustain all in-rush and operating currents.
