Voltage current adjustable power supply circuit is based on LM723 voltage regulator IC, the power transistors used are 2 bd249 input voltage dc 40 volt dc 1volt 37volt voltage adjustment 40 mA 3 ampere current adjustment. Also, two pots are used for current adjustment, so precise adjustment can be made. .
The regulated part of the circuit can be made as a separate floor or you can edit the pcb file. For rectification, kbu808 bridge or 4 diodes of 6 amps can be used, filter capacitor 10000uf.
