adjustable power supply 30v

Adjustable power supply 0 – 30V / 1A

This power supply deliver a cc voltage adjustable between 0 and 30V , a current intensity of 1A and has a built in programmable current limitation.
The output current can be adjusted with P3.

Power supply first use adjustment
Load the output with a 1k / 1W resistor, rotate P3 at minimum and adjust P2 untill his cursor is next to the + output voltage line. With P1 bring the output voltage to 0. If the adjustment domain of the P2 potentiometer does not reach 30V, lower R6 value.
