The numerical control D. C. power-supply circuits-fixed introduced in the example uses control button to choose output voltage (range:1.5-15V)and adopts LED to indicate the magnitude of voltage,which is convenient and intuitionistic.
Work's Principle of the Circuit
The numerical control D. C. power-supply circuits-fixed is omposed of power-supply circuits-fixed and ouput voltage control circuitand it is showed as the picture 5-24.
The power-supply circuits-fixed consists of mains switch,S1,mains tranformer,T,rectifier bridge,UR,capacitor,C1-C3,three-terminal integrated regulator,IC1and IC2 and resistor,RO-R1O.
