Arduino Digital Bench Power Supply

A bench power supply is an extremely handy bit of kit to have around for electronics hobbyists but they can be expensive when purchased from the market.

Arduino digital bench power supply.

The power supply is controlled by an arduino and a touchscreen tft screen is used to monitor and control it. I would like to make here the following explanations. The former solutions are in general open source with limited feature set and without support for some standardized way to communicate with them e g. A perfect project for beginners and experts alike.

Watch the video and give your comments. This article describes a rather nice solution for building a current and voltage controlled benchtop power supply using a dc supply in the range of 20 30 volts and some additional down regulation circuitry with current and voltage control provided by an avr microcontroller in a feedback loop. The programmable bench power supply psu is an attempt to bridge the gap between so many simple hobbyists diy power supplies and commercial solutions trying to combine the best ingredients and practice from both sides. The programmable bench power supply project was an attempt to create reliable modular open and programmable power supply that can be used for various tasks starting with powering breadboard charge or to some extent.

Hello all and welcome to my first instructable i ve always wanted a bench psu for easy access to a power source and something that i can rely on when working on various projects. The important thing is this power supply is kind of a bench power supply and it can change the voltage from 0 to 30 v and 0a to 3a a current. I wanted a psu that. 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.

Bench psu power supply from old atx with arduino and lcd monitor. I like the idea and i d like to build my own but i think the interface is a bit kludgy so i d. It comes with a bunch of features you can check on the link below. Build a safe and simple bench power supply with a fixed and variable output digital display and memory.

Variable voltage 0 25v presize current limiting mode based on lm 317 lm358.
