STRIDER SST-ST60F

3. PROTECTION

3.1 Over-power protection

The power supply will be shutdown and latch off when output power is 110%~150%.

3.2 Over voltage protection

The over voltage sense circuitry and reference shall reside in packages that are separate

and distinct from the regulator control circuity and reference.No single point fault shall be

able to cause a sustained over voltage condition on any or all outputs.The supply shall

provide latch-mode over voltage protection as defined in Table.

output Minimum Nominal Maximum Unit

+12V1DC or +12V2DC

output Minimum Nominal Maximum Unit

+12V1DC or +12V2DC

3.3 Under voltage protection

The under voltage sense circuitry and reference shall reside in packages that are separate

and distinct from the regulator control circuity and reference.No single point fault shall be

able to cause a sustained under voltage condition on any or all outputs.The supply shall

provide latch-mode under voltage protection as defined in Table.

3.4 Over Current Protection

+5VDC, +12V1DC, +12V2DC and +3.3VDC have separate over current protection circuits

to meet 240VA safety requirement.

3.5 Short circuit

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 +3.3VDC,+5VDC,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.
