0 30 V 2Amp POWER SUPPLY (VARIABLE)

Make a DIY variable power supply using a transformer, 2N3055 transistor, and 741 op-amp to control the voltage. This project is perfect for electronics enthusiasts and students. Components: - Transformer (12V-0-12V,3A) - 2N3055 Transistor, 2 nos. - 741 Op-Amp - Potentiometer (1kΩ,5kΩ) - Resistors (1kΩ, 2kΩ, 2.2Ω(5W)) - Capacitors (100nF, 4700uF) - Diodes (1N4007) - 8 pin IC base - Heat Sink Circuit Description: The circuit uses a transformer to step down the AC voltage, which is then rectified and filtered to produce a DC output. The 741 op-amp is used as a voltage regulator, controlling the base of the 2N3055 transistor to regulate the output voltage. The potentiometer is used to adjust the output voltage. Features: - Adjustable output voltage (0-30V) - Current limit: 2A - Short circuit protection - Overload protection Applications: - Electronics testing and debugging - Powering small circuits and projects - Educational purposes
