SilverStone ST65F-GS [6/12] Under voltage protection

3.2 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.

3.3 Over-power protection

The power supply will be shutdown and latch off when output power within 105~150% of rated

DC output.

Note: Assurance machine can work at low voltage,full load won't damage machine.

3.4 Under voltage protection.

In an under voltage fault occurs, the supply will latch all DC outputs into a shutdown state when

+12V,+5V & +3.3V outputs under 85% of it's maximum value.

3.5 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 +5Vdc and +3.3Vdc and +12Vdc supply

shall provide

latch-mode over voltage protection and +5Vsb shall provide recover automatically as defined in Table.

3.6 Short circuit

3.7 No load operation

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

No damage or hazardous condition should occur with all the DC output connectors disconnected from

the load.The power supply may latch into the shutdown state.
