Adjustable DC Regulated Power Supply Kit
Power supply kit features:
• High-quality DC regulated power supply whose output voltage is continuously adjustable from 0 to 30V.
• Including a circuit to limit output current which enables output current to be continuously adjustable from 2mA to 3A.
• Provides current limiting.
• Overload and short circuit protection.
• Easy to install and maintain.
Note: This kit is not assembled but comes with the diagrams and everything to assemble it yourself. Below is a picture of how it will look once you assemble it.
Note: Please install the resistors and diodes according to PCB diagram. Make sure resistance values, diode models and installation direction are correct. Please install other components from small to large, low to high.

I have build 5 of these power supply units, awesome kit. Modified 2 of them to to give 30Volt and 40Amp. Perfect for Lab work and precision circuit testing. Based on a circuit designed in 1978 and published in the Everyday Electronics magazine.
Well, if I can find a 24V AC transformer somewhere, or a 24VAC power supply - I would test it. But it has been sitting on my shelf, after assembly, waiting for the elluding 24VAC :(
Well made kit. Went together easy. Would've been nice if it came with a heatsink for the power transistor but other than that it works just fine.
