Power Module Input
Voltage:
208/220/240Vac (continuous operation 90-300Vac)
High: 277 to 300Vac (de-rated power factor)
Low: 90 to 176Vac (de-rated output power)
Frequency:
50/60Hz nominal (45 to 66Hz)
Current:
7.5A maximum (176 to 300Vac)
6A maximum (90 to 176Vac)
Power Factor:
>0.99 at nominal conditions and 50-100% load
Protection:
10kA-interrupting capacity fuses in active and neutral lines
Efficiency:
>93% at nominal conditions and 50-100% load
Inrush Current:
≤
full load steady state current of the rectifier within rated limits
Start-up Ready Time:
<5 seconds (excluding soft start) to complete inrush limit routine and ac
measurement (for OK signal)
Start-up Delay:
Programmable up to 120 seconds to enable stagger-start of multiple rectifiers
and to minimize the effect on a supply source
Soft Start:
User adjustable to at least 5 seconds (not including start-up delay time) and is
determined by output current limit ramp-up
T.H.D. (Current):
<5% at 100% load for 208 to 220Vac
Input Transient Suppression:
Meets ANSI/IEEE C62.41 Category B3
Input Leakage Current:
<3.5mA @ 265Vac 60Hz for up to two rectifiers*
>5mA @ 265Vac 60Hz for three or more rectifiers*
[*plugged inside 1RU or 2RU shelf]
