Universal Power Supply for Everything

Hello Friends as a electronics hobbyst we all need a power supply on work bench, we also need -ve rail power supply to power various electronics Eg- OpAmp etc. today in this part i am going to shere a very common type power supply made up of common electronics components,.For more Detailed info please visit my channel or watch video above.

In this Project 12-0-12 volt center tapped transfarmer is used to step down mains voltage, as it is more robust and easy to handle rather then SMPS, because of its simplicity i utilize it in my project.

KA7912 is used to regulate -ve Rail of power supply As this is very simple to use in this project.

Pin1= GND(common)

Pin2= -ve Input

Pin3= Output

LM7812 used in this project to regulate +ve supply Rail to +12v.

Pin1= Input

Pin2= GND(Common)

Pin3= Output

Bridge rectifier is used in this project to convert AC signal to DC , Bridge rectifier can be made using 4 Diodes. IN4007 (1000volt 1Amp).

Capacitor used in this project used to convert pulsating DC to Smooth DC. To ensure good stability.

Assamble all the components as shown in circuit diagram.

All Components are assembled in PCB. If you want to see it working you can also check my video
