Over Voltage Protection (OVP)

The power supply over voltage protection shall be locally sensed. In an over voltage fault
occurs, the supply will latch all DC outputs into a shutdown state except 5Vsb output. This latch
shall be cleared by an AC power interruption. Table 13 contains the over voltage limits. The
values are measured at the output of the power supply's connectors. The voltage shall never
exceed the maximum levels when measured at the power pins of the power supply connector
during any single point of failure. The voltage shall never trip any lower than the minimum
levels when measured at the power pins of the power supply connector.
Output Voltage
+5V
+3.3V
+12V

2.4.3 Short Circuit Protection (SCP)

The power supply shall shutdown and latch off for shorting +3.3V, +5V, -5V, +12V or -12V rails.
The main output short circuit of any impedance shall be less than 0.1 ohms. The maximum
short circuit current in any output shall not exceed 240VA.
