Description
Description
The circuit described in this page represents a variable power supply based on the integrated LM 317, the PCB measures 28x47 mm.
Once assembled, all the only calibration required will be to change the value of Trimmer P1 until the desired value is obtained. In case the integrated unit should heat up, a cooling fin must be installed.
