3.2.6
The 650-W 2+1 RPS power supply incorporates two high performance 60-mm fans to exhaust air.
If a module failure is detected, the fans will enter a faster boost mode to provide additional cooling
until the failing module is replaced. Under a condition where one module has failed, it is
acceptable for the sound pressure level to approach 72 dBA (maximum).
The fans are redundant when 3 modules and 2 power cords are present. In this case, if a fan fails,
the remaining fan will enter boost mode and maintain proper cooling. If the second fan fails,
module fails, or a power cord is removed, the power supply will shut off.
3.2.7
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 similarly ±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. Further details on these waveforms
can be obtained in ANSI/IEEE STD C62.45-1992.
