4.1.6.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 or
output, the power supply
will shutdown and latch off without damage to the power supply. 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 an output short circuit condition on -12Vand -5V output, the power supply will not
be damaged. 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.

4.1.8.POWER GOOD SIGNAL
The power good signal is a TTL compatible signal for the purpose of initiating an orderly star-up
procedure under normal input operating conditions. This signal is asserted (low) until +5Vdc has
reached 4.75 volts during power up. Characteristics:
TTL signal asserted (low state) : less than 0.5V while sinking 10mA.
TTL signal asserted (high state): greater than 4.75V while sourcing 500uA.
High state output impedance: less or equal to 1Kohm from output to common.
