The power of 8.5KW load off can be controlled by using the input phototransistor BPY62 and power operational amplifier.The voltage divider composed of two 10KΩ resistors connects to the inverting input terminal of the voltage divider, so that the turnover voltage of the amplifiers is 1/2 US. Switch sensitivity can be adjusted in the range of 10 - 10 quadruplicate lx by using potentiometer. The output of the circuit is controlled by contactor coil.
