Hello my dear friends,
in this blog i am going to show you that how to make a cheap Regulated DC Power Supply / Lab bench Power Supply Tools. We know that it's a very essential tools for our electronic works. because it's gives you various voltage ans Amps range between 0-30 volt (10 Amps) as per our projects requirements. it's also available on market but very costly, So let's make it ourselves.
If you want to buy some readymade power supply, here is the link below, you can buy it online
So we need following materials / Parts to make this Power Supply Unit.
- 1x LM 317 Regulator Integrated
- 2 x .1uf Capacitor
- 1 x 5K Potentiometer
- 1 x 10K Potentiometer
- 1 x 220R Resistor
- 1 x 1K Resistor
- 1 x 5mm LED
- 2 x 0.10R to 1R 5W Resistor
- 1 x 1000uF 35V Capacitor
- 1 x BD139 Transistor
- 2 x TIP3055 Power Transistor
- 2 x Aluminum Heatsink
