The Variable Regulated Power Supply can provide the 1.5V to 30V.In this kit there is LM317 IC is used.This is simple circuit using this circuit we get the 1.5V to 30V it is variable and the current is 1.5A.

Working/About the Circuit:

First you need the transformer to convert the 220V AC to 24V AC.Then the next connected this circuit from the bridge rectifier D1-D4 here rectified from AC to DC.The LM317's max input voltage is 36V.D5 is the feedback diode it prevent the circuit for damaged.Here we used the R1 resistor because when the power is down then the attach led is on


  • variable power supply
