SHORT CIRCUIT PROTECTION
Output short circuit is defined to be a short circuit load of less than 0.1
ohm.
In the event of an output short circuit condition on +3.3V, +5V or +12V
output, the power supply will shutdown and latch off. The power supply
shall return to normal operation after the short circuit has been
removed and the power switch has been turned off for no more than 2
seconds.
OVERLOAD PROTECTION
Overload currents defined as a 10 amp/sec fault current ramp starting
from full load, applied to the +3.3V, +5V output, shall not cause that
output to exceed 32 amps before the output voltage drops below 0.5
volts and is latched off. The +12V output shall not exceed 20 amps
under the same ramp conditions starting at full load before it is latched
off.
