2.3 Output Ripple
2.3.2 Definition
2.3.3 Ripple voltage test circuit
2.3.1 Ripple regulation
2.4 Overshoot
Any overshoot at turn on or turn off shall be less 10% of the normal voltage value, all
outputs shall be within the regulation limit of section 2.0 before issuing the power good
signal of section 5.0.
2.5 Efficiency
Power supply efficiency typical 10% load/90%, 20% load/92%, 50% load/94%, 100%
load/90% at 115V AC voltage on all outputs.
The ripple voltage of the outputs shall be measured at the pins of the output connector when
terminated in the load impedance specified in figure 1. Ripple and noise are measured at the
connectors with a 0.1uF ceramic capacitor and a 10uF electrolytic capacitor to simulate
system loading. Ripple shall be measured under any condition of line voltage, output load,
line frequency, operation temperature.

3. PROTECTION
3.1 Over current protection
3.2 Over Temperature Protection
The power supply shall have current limit to prevent the +3.3V,+5V,and +12V outputs from
exceeding the values shown in the following Table. If the current limits are exceeded the
power supply shall shutdown and latch off.
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
restore power automatically. The OTP circuit temperature drops to within specifide limits,
the power supply shall restore power automatically. The OTP circuit condition.
3.3 Over-power protection
The power supply will be shutdown and latch off when output power within 110~160% 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.
ST60F-TI
When the logic level "PS-ON" is low, the DC outputs are to be enabled.
When the logic level is high or open collector, the DC outputs are to be disabled.

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 from the regulator control circuity and reference. No single point
fault shall be able to cause a sustained as defined in Table.
3.6 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 +3.3 VDC,+5 VDC,or+12 VDC 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
3.7 No load operation
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.
