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.
