The control DC regulated power supply circuit introduced in the example uses light touch buttons and digital integrated circuit to control the output low voltage of voltage regulation circuit.Its output voltage range is 1.5-30V.The circuit uses 20 reversible gears stepping control(stepping value is 1.5V).The low voltage gear is 1.5-15V(zero to ninth gear) and high voltage gear is 16.5-30V(tenth to ninth gear) and the output votage gear is indicated by LED digital display. Circuit's Work PrincipleThis control DC regulated power supply circuit is composed of voltage regulation circuit,control circuit and gear indication circuit and it is showed as the picture 5-25. Voltage regulation circuit consists of mains switch,S1,gear selector switch,S2a ,FU1-FU3,mains transformer,T, rectifier diode ,VD10,capacitor,C1-C7,voltage regulator IC,IC4 and resistor,RO.
