Over-Voltage Protection (OVP)

Output Voltage Maximum Voltage

+5V6.5V

+3.3V4.6V

+12V15.5V

+5VSB7V

The power supply will shut down and latch off for shorting +5V, +12V,

-12V, or +3.3V. By shorting +5VSB, the power supply can latch down or automatically recover when the fault condition is removed
