G-1-5: SHORT CIRCUIT PROTECTION
Output short circuit is defined to be a short circuit load of 0.1
ohm. In the event of short circuit condition on +3.3V, +5V or
+12V, 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.
In the event of short circuit condition on –12V, the power
supply will not latch off. The power supply shall return to
normal operation as soon as the short circuit has been
removed and the power switch has been turned off for no
more than 2 seconds.
