摘要：A power supply voltage detecting circuit includes a voltage regulating circuit, acomparative circuit, a timer circuit, and a display circuit. The voltage regulating circuitprovides a stable reference voltage to the comparative circuit. The comparative circuitcompares the reference voltage with the voltage from the power supply. The

comparative circuit is electrically connected to the display circuit via the timer circuit. Thedisplay circuit includes light emitting diodes for revealing a status of the voltage from thepower supply. The timer circuit causes the display circuit to keep a light on when therehas been an occurrence of abnormal voltage from the power supply until an operatorresets it.
