Power Good信号简称“P.G.”或P.OK信号。该信号是直流输出电压检测信号和交流输入电压检测信号的逻辑与TTL信号兼容。当电源接通之后,如果输入交流电压在额定工作范围之内,且各路直流输出电压也已达到它们的最低检测电平(+5V输出为4.75V以上),那么经过100ms～500ms的延时,P.G. Power Good signal referred to as “P.G.” or P.OK signal. This signal is compatible with the TTL signal logic of the DC output voltage sense signal and the AC input voltage sense signal. When the power is turned on, if the input AC voltage within the rated operating range, and each DC output voltage has reached their minimum detection level (+ 5V output is 4.75V or more), then after 100ms ~ 500ms delay , PG
