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.
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.
