The output voltage of the numerical control D. C. power-supply circuits-fixed introduced in the example is from +1.5V to 12V with 8 adjustable grades and its maximum current is 1.5A. Work's Principle of the Circuitnumerical control D. C. power-supply circuits-fixed consists of +12V voltage constant voltage control circuit,voltage control or indication circuit and constant voltage output circuit and it is showed as the 5-28 picture. The +12V voltage constant voltage control circuit consists of mains switch,SO,mains transformer,T,rectifier bridge,UR,resistor,RI,voltage regulator diode,VS,and filter capacitor,C1,C2,C7.The voltage control or indication circuit is composed of reset button,S1,control button,S2,resistor,R2-R6,regulation resistance,RP and capacitor,C5,C6,C8
