3.7 PG-OK PG-OK is a power good signal and should be asserted high by power supply to indicate that the +5 VDC and +3.3 VDC outputs are above the under-voltage thresholds of the power supply. When this signal is asserted high, there should be sufficient mains energy stored by the converter to guarantee continuous power operation within specification. Conversely, when either the +5VDC or the +3.
4.2.4 Short Circuit Protection Short circuit placed on +5V,+12V,+3.3V,-12V will latch off. +5VSB will auto-recovery. 4.2.5 Over-Current Protection Current protection should be designed to limit the current to operate within safe operating conditions.
8. Product Safety 8.1 Safety Requirement cTUVus, CB,TUV 8.2 Leakage Current The AC leakage current is less than 3.5mA when the power supply connect to 264Vac/50Hz . 8.3 Insulation Resistance The insulation resistance should be not less than 30M ohm after applying of 500VDC for 1 minute. 8.4 Dielectric Voltage Withstand The power supply shall withstand for 1 minute without breakdown the application of a 60Hz 1500V AC voltage applied between both input line and chassis (20mA DC cut-off current).
