Description______
In this video i'm showing how to make a
Variable power supply with both voltage & current control 1-30 volts and 0-10A.
Both voltage and current can be controlled with Potentiometers, Multi-turn potentiometers is good for high precision settings. Where output load should be under 10 Amperes.
And required big heatsink with cooling fan for effective cooling.
Also required DC Volt Ampere meter to monitor the output.
Parts Required_____
TIP3055 & BD139 Transistors
LM7805 & LM317 voltage regulators
10k, 220 ohms resistors + 1 LED
10k Multi-turn potentiometers
2x 1N4007 diodes
1x 5v dc cooling fan
1x DC volt cum Ampere meter
