4. Protection
Protection circuits inside the power supply shall cause only the power supply’s main outputs to
shutdown. If the power supply latches off due to a protection circuit tripping, either a AC cycle OFF
for 15 sec, or PSON# cycle HIGH for 1 sec must be able to restart the power supply.
4.1 Over Current Protection
This power supply shall have current limit to prevent the +5V, +3.3V, and +12V outputs from
exceeding the values shown in table 14. The current limit shall not trip under maximum continuous
load or peak loading. The power supply shall latch off if the current exceeds the limit. The latch
shall be cleared by toggling the PSON# signal or by cycling the AC power. The power supply
shall not be damaged from repeated power cycling in this condition. The -12V and +5VSB outputs
shall be shorted circuit protected so that no damage can occur to the power supply.
Table 14 –Over Current protection
4.2 Over Voltage Protection
The power supply shall shut down in a latch off mode when the output voltage exceeds the
over voltage limit.
Table 15 –Over Voltage protection
4.3 Short Circuit Protection
The power supply shall shut down in a latch off mode when the output voltage is short circuit.
