② Short Circuit and Over current Protection
An output short circuit is defined as output impedance of less than 300mohms. The power supply shall shutdown and latch off for
shorting VS DC rails to return. Shorts between main output rails and STD_5V shall not cause any damages to the power supply.
The power supply shall either shutdown and latch off for shorting is removed, the P/S shall recover. The power supply shall be
capable of withstanding a continuous short-circuit to the output without damage or over stress to the unit (components, PCB
traces,connectors,etc.) under the input conditions specified in Section 3 above. Current Protection as defined below.
