0-30V Laboratory Power Supply

This project is based on the 0-30 VDC Stabilized Power Supply with Current Control 0.002-3 A and a new PCB layout is introduced here. It’s a stabilized power supply with variable output voltage in the range 0-30Vdc (33Vdc peak) – and variable current 3A and is ideal for your laboratory power supply.

Description


Schematic and PCB are designed in Eagle software and the source files are available on the links at the bottom of the page. The PCB design has connectors for 2N3055 transistor, input and output voltage. Also on-board potentiometers are added.
