The power supply circuit is composed of the step-down capacitor C1, discharge resistor RI, rectifier diodes VD1, YD2, filter capacitor C2 and zener diode VS. Temperature detection control circuit is composed of the thermistor RT, resistors R2, R3, potentiometer RP, light-emitting diode YL, three-terminal precision regulator integrated circuit IC and thyristor VT. RI selects the l/2W metal film resistor: R2 and R3 select the l/4W metal film resistor. RP uses the multi-turn potentiometer. vs uses the 2DW7 silicon zener diode.
