Variable power supply 0-30V 1A using transistors
This is simple Variable power supply 0-30V 1A projects. I use the transistor 2SC1061 or H1061. It used for control current up to 1 Amp. The circuit use transistor 3 pcs only, it very small circuit. The Q3-C1061 must hole heat sink with. VR1 for control voltage 0-30V at 1A …
