Adjustable Power Supply Circuit Diagram. What is a variable power supply. The power circuit designed in this project can be used as a constant current source regulator or an adjustable power supply of 1 25 v to 37v dc.
In this project i have designed a simple adjustable voltage dc power supply using the lm317 ic with an lm317 power supply circuit diagram. Here is a project of a 1 25v to 37v 5 amp power supply circuit using lm338 ic. As this circuit has an inbuilt bridge rectifier so we can directly connect 220v 110v ac supply at the input.
The circuit converts 230volt 110volt ac to 0 12volt dc.
In this project i have designed a simple adjustable voltage dc power supply using the lm317 ic with an lm317 power supply circuit diagram. R1 0 33 ohms 5 watt wire wound r2 r4 680ohms watt. Hey guyz this time i m making a variable bench power supply this is the most useful equipment for a hobbyist and diy maker cause while making or testing circuits it needs different values of voltage and current. It will keep a stable voltage when it has any load.
