Variable Power Supply with Adjustable Current Limit
This circuit variable power supply with adjustable current limit using three terminal adjustable regulator LM117 which is used to regulate current and the voltage limits. Variable power supply input range is between 32 V to 40 VDC and can provide outputs up to 25 VDC and provide currents up to 1.2 A Dioda D2 and D3 and Q2 are added to allow adjustment of output voltage to 0 volts. D1 protect both LM117 during an input short circuit
