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

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.

 

 

Max input current slew rate
