Electronic pests killing lamp circuit diagram 8
The electronic pests killing lamp circuit is composed of the power supply circuit, pulse oscillator and high-voltage generator circuit, and the circuit is shown as the chart. Power supply circuit is composed of the power switch S, fuse FU, power transformer T1, rectifier diodes VD1 ~ VD4, filter capacitors C1, C3, three-terminal voltage regulator integrated circuit IC1, limiting resistor RI and power indicator light-emitting diode VL. Pulse oscillator is composed of the time-base integrated circuit IC2, resistors R2, R3, potentiometer RP1 and capacitors C2, C4. High-voltage generator consists of transistors V1, V2, potentiometers RP2, RP3, resistors R4, R5, pulse transformer and high-voltage grid ( high voltage electrodes A, B). EL is the trapping light; C5 is the buck capacitor.
