ST85F-GS / ST75F-GS

2.3.3 Ripple voltage test circuit

2.4 Overshoot

Any overshoot at turn on or turn off shall be less 10% of the norminal 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 87% for 750W 850W normal voltage at full load on

all outputs.

2.6 Remote ON/OFF control

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.

3.1 Over current protection

The power supply shall have current limit to prevent the +3.3V,+5V,and +12V1,+12V2

outputs from exceeding the values shown in the following Table.If the current limits are

exceeded the power supply shall shutdown and latch off.
