AC Power Line
The system is specified to operate from 100-127VAC, 200-240VAC, at 50 or 60 Hz. The
specified PFC power supplies are auto-ranging. The system is tested to meet these line
voltages, and has been tested, but not specified, at
specified PFC power supplies are auto-ranging. The system is tested to meet these line
voltages, and has been tested, but not specified, at
±10% of the voltage ranges, and at ±3 Hz
on the line input frequency.
The system is specified to operate without error at full power supply output load, nominal input
voltage, with line source interruptions not to exceed one period of the AC input power frequency
(i.e., 20 milliseconds at 50 Hz).
voltage, with line source interruptions not to exceed one period of the AC input power frequency
(i.e., 20 milliseconds at 50 Hz).
The system is not damaged by AC surge ring wave up to 2.0kV/500A. This ring wave is a 100
kHz-damped oscillatory wave with a specified rise time for the linear portion of the initial half-
cycle of 0.5
kHz-damped oscillatory wave with a specified rise time for the linear portion of the initial half-
cycle of 0.5
µsec. Additionally, the system will not be damaged by a unidirectional surge
waveform of up to 2.0kV /3000A, with a 1.2
µsec rise time and 50µsec duration. Additional
details on these waveforms can be obtained in ANSI/IEEE STD C62.45-1992.
