Rosewill RP550-2 Power Supply User Manual


 
3.2 Short Circuit Protection
A short circuit on any DC output will cause the power to latch. The power supply will
withstand a continuous short circuit to the output without damage or overseers to the
unit. The +5VSB can be shorted indefinitely and will recover automatically when the
short is removed.
3.3 No Load Operation
No hazardous conditions or damage to the supply will occur with all of the DC output
connectors disconnected from the load.
3.4 Over Power Protection(OPP)
The power supply shall go shutdown when the total output load is over 110-160% of
rating.
3.5 Over Current Protection
Overload currents applied to +12V1&+12V2 will cause the output to trip before reaching
or exceeding 240 VA. For testing purposes, the overload currents should be ramped
at a minimum rate of 10 A/s starting from full load.
4. Physical Environment
4.1 Operating Conditions
The power supply shall be capable of continuous operation and meet all electrical
specification without need for adjustment when subjected to the following
environ-mental conditions:

4.2 Shocks & Vibration
The power supply will withstand the following imposed conditions without experiencing
non-recoverable failure or deviation form specified output characteristics.
Storage -40G, 11mSec. half-sine wave pulse in both directions on three mutually
perpendicular axes. Operating -10G, 11mSec. half-sine wave pulse in both directions
on three mutually perpendicular axes. Vibration Operation-Sine wave excited, 0.25G
maximum acceleration, 10-250 Hz, swept at one octave/mine. Fifteen-minaret dwell at
all frequencies at which the device under test experience excursions two times large
than non-resonant excursions.
