The numerical control D. C. power-supply circuits-fixed introduced in the example controls the magnitude of the voltage by touching the sheet metal by fingers.Its magnitudeof the output voltage are divided into 8 gardes ,namely,1.5V,3V,4.5V,6V,7.5V,9V and 12V which uses LED to indicate and it's convenient. Work's Principle of the Circuit The numerical control D. C. power-supply circuits-fixed is composed of trigger generator circuit and counter,encoder,,switch control circuit and constant voltage and it is showed as the picture 5-31. The trigger generator circuit consists of touching sheet metal,A1,A2,NOT-gate IC1(D1-D4),NOT-gate IC,IC2(D5,D6),resistor,R1-R4,capacitor,C1-C4.
