This is high quality 0-30v stabilized variable power supply circuit diagram. You will able to adjust the output voltage from 0 volt up to 30 volt DC. You also able to adjust the current output value from 0.002 A to 3 A. This variable power supply incorporates an electronic output current limiter that effectively controls the output current from a few mA (2 mA) to the maximum output of 3 A that the circuit can produce.

hello, all,
i 63 years old man and have not any job with me,
I m searcing on web. for electronic,
if any body need a pcb lay out of any schematic i will make and provide in adoba formate (free of cast)
if needed PCb then one PCB ian provide but it will chage the price for the material paking postage etc,
waiting for yuor choice
Thank you
