Power Module Input
Voltage:
Nominal: 208-240Vac
Extended: 90-276Vac
Extended Low: 60-90Vac (derated linearly to 0% output power)
Extended High: 276-320Vac (derated input power factor)
Frequency:
50/60Hz nominal (45 to 66Hz)
Current:
1.7 to 2.0A (208-240Vac), 5.2A maximum @ 90Vac
Power Factor:
>0.98 at 208-240Vac and 50-100% load
Protection:
1.5kA-interrupting capacity fuses in active and neutral lines
Efficiency:
>87% at 208-240Vac and 50-100% load
92.2% peak
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 measure-
ment (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 de-
termined by output current limit ramp-up
THD (Current):
<6% at 100% load 208-240Vac
Input Leakage Current:
<3.5mA @ 265Vac 60Hz for up to two rectifiers
