Intel® Entry Server Chassis SC5250-E Chassis Power Subsystem

Revision 1.02

Intel order number C32881-001

3.1.3 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 ±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).

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 0.5µsec. Additionally, the system will not be damaged by a unidirectional surge

waveform of up to 2.0kV /3000A, with a 1.2µsec rise time and 50µsec duration. Additional

details on these waveforms can be obtained in ANSI/IEEE STD C62.45-1992.
