Interface Signals and Internal Protection Parameter Conditions/Description The power supply will be turned on when the power On/Off pin is connected to secondary Power On/Off GND. When power is turned on, the power good signal will go high 100ms to 500ms after all Power Good Signal output DC voltages are within regulation limits. The power fail signal will go low at least 1ms before any of the output voltages fall below Power Fail Signal the regulation limits. (Note 1) Short Circuit Protection Fully protected against short circuit. Latch off mode upon of short circuit condition . Over Voltage Protection For some reason the power supply fails to control itself, the build-in over voltage protection circuit will shut down the outputs to prevent damaging external circuits. The trigger point is 7V max. at +5V. If the OVP occur, PSU cannot be recovered. Over Temperature When the power supply operating over the temperature or over load limit, the power Protection supply will be shut down automatically to protect itself. The protection point is at the temperature of the HS1 over 110°C. After the temperature of HS1 going down, the power supply will restart automatically. Note: 1) Only +5Vsb and -12V is protect by auto recovery. 5. Safety Approvals, EMI and EMS Specification Parameter Conditions/Description Min. Nom. Max.
