The output voltage of the numerical control D. C. power-supply circuits-fixed introduced in the example are divided into 8 grades,namely,3V,4.5V,5V,6V,7.5V,9V,l2V and l5V.Its maximum current is 2A. Work's Principle of the Circuit The numerical control D. C. power-supply circuits-fixed consists of constant voltage control circuit and touch control circuit and it is showed as the picture 5-29. The constant voltage control circuit is composed of mains switch,S,fuse,FU,mains transformer,T,rectifier bridge,UR,filter capacitor,C1 and five-terminal adjustable integrated regulator,IC2.The touch control circuit is composed of touch electrode slice,A1-A8,resistor,R1-R6,transistor,V1-V8 and electronic switching IC,IC2.
