The latest shown here in action was almost perfect two channels 1 2 30v 3a but there wasn t current limiting.
Digital lab power supply schematic.
I had just built today this power supply using the schematic and pcb lay out and everything works fine maybe you have a bad solder or some parts are wrongly placed recheck all connections and all soldered points it should looks shiny if properly soldered.
Digital control for laboratory power supply using arduino.
In this project i will show you how i combined a ltc3780 which is a powerful 130w step up step down converter with a 12v 5a power supply to create an adjustable lab bench power supply 0 8v 29 4v 0 3a 6a.
The output of ic1 is connected via an rc network to the clock input of counter ic cd4017 ic2.
I already have several lab power supplies all of them made by myself.
In this instructable i will show you how to make a variable lab bench power supply with a limited budget it is a great diy project for beginners as well as any one interested in electronics.
