Protection

Due to overvoltage, over power and short circuit, the protection function of
the power supply circuit is self operated, and the power is self locked. There is no output at that time. When these reasons are removed, the power is restored to the normal output state when the power is restarted. (PSON# at least 1 second;
AC shutdown at least 4 seconds).

Over-power protection.
The power supply will be shutdown and latch off when output power within 110~150% of rated DC output.
Note: Assurance machine can work at low voltage,full load won’t damage machine.

Over voltage protection:

Short circuit protection:
An output short circuit is defined as any output impedance of less than 0.1 ohms. The power supply shall shut down and latch off for shorting the +3.3 VDC,
+5 VDC,or+12VDC rails to return or any other rail. Shorts between main output rails and +5VSB shall not cause any damage to the power supply.
The power supply shall either shut down and latch off or fold back for shorting the negative rails.+5VSB must be capable of being shorted indefinitely,
but when the short is removed,the power supply shall recover automatically or by cycling PS_ON#.The power supply shall be capable of withstanding a continuous short-circuit to the output without damage or overstress to the unit

Over Temperature Protection:
The power supply will be protected against over temperature conditions caused by loss of fan cooling or excessive ambient temperature.In an OTP condition the PSU will shutdown. When the power supply temperature drops to within specifide limits,the power supply shall Lacth mode.

Over current protection
The power supply shall have current limit to prevent the +3.3 V, +5 V, and +12V outputs from exceeding the values shown in Table . If the current limits are exceeded the power supply shall shutdown and latch off. The damaged from repeated power cycling in this condition. -12V and 5VSB shall be protected under over current or shorted conditions so that no damage can occur tothe power supply. All outputs shall be protected so that no damage occurs to the power supply under a shorted output condition.
