HOW TO MAKE A VARIABLE POWER SUPPLY ( VOLTAGE AND CURRENT CONTROL )
HOW TO MAKE A VARIABLE POWER SUPPLY
In this video I have made a variable power supply using an adjustable voltage regulator LM 317 and a power transistor to increase its output current . I have tried to make this video as easy as it could be and used common components. I Hope it would be helpful
COMPONENTS:
1- 1X LM 317
2- 1X D1047 TRANSISTOR
3- 1X BD139 TRANSISTOR
4- 1X 5 K OHM VERIABLE RESISTOR
5- 1X 10 K OHM VERIABLE RESISTOR
6- 1X 4.7 K OHM RESISTOR
7- 1X 4.7 OHM 10 WATT RESISTOR
8- 1X 220 OHM RESISTORS
9- 1X LED
10- 2X2 PIN TERMINAL BLOCKS
11- HEAT SINKS
12- 1X VERO BOARD
13- SOME WIRES
