How It WorksHow to BuildsParts ListsTesting and RepairAnswer The Question- FAQCan Adapt to 0-70V Variable Power Supply?Can Increase Current Up to 5A?Figure 1 is the circuit diagram of this projectt of all, the AC-voltage from the transformer-T1 flows through diode D1-D4 to the rectifier to DC voltagend, capacitor-C1 filters that pulsed DC voltage to smooth, before sent through R1, R2 into TR5.0-50V 3A variable power supply circuitAnd there are IC1 is used to control a voltage at OUT point by adjusting VR1 can adjust voltage between 0-50 volts.See more on eleccircuit
Variable Voltage Power Supply Using The LM317T
ExampleSpecificationsApplicationsOperationFunctionAdvantagesPerformanceIntroductionMechanismContinuing on from our tutorial about converting an ATX PSU to a bench power supply, one very good addition to this is the LM317T positive voltage regulator. So suppose we want an output voltage of +9 volts from our PSU bench power supply, then all we have to do is connect a +9v voltage regulator to the +12V yellow wire. As the PSU has already done the rectification and smoothing to the +12v output, the only additional componentSee more on electronics-tutorials

0-30V Variable Power Supply circuit Diagram at 3A
This is a 0-30V Variable Power Supply circuit diagram. I recommended this. Because you can adjust an output voltage of 0V to 30V, at 3A current, and overload protection. Also, It is a high-efficiency regulator using IC regulator, UA723, and power transistor, TIP3055. So, it is small laboratory DC Power Supply in inexpensive cost.
0-30 Vdc Stabilized Power Supply with Current Control 0
This is a high quality power supply with a continuously variable stabilised output adjustable at any value between 0 and 30VDC. The circuit also incorporates an electronic output current limiter that effectively controls the output current from a few milliamperes (2 mA) to the maximum output of three amperes that the circuit can deliver.
