Power supply with adjustable voltage and current. But not a powerful DC voltage controller.
- Power supply with adjustable voltage and current. You can supply an input maximum of 12V to 20V, 5A - 10A. It includes variable voltage and variable current feature, fully adjustable. This is the most useful equipment for a hobbyist and DIY maker cause while making or testing circuits, it needs different values of voltage and current. The supply must also be safe from a short circuit throughout its output and be able to restricting the load current to ensure that devices are not damaged by failing circumstances. It is a regulated power supply, which means that the output voltage and current are constant, regardless of changes in the input voltage or load. The SMPS concept today has almost completely replaced the traditional iron core transformers and have transformed Apr 2, 2024 · RJ TECH - Unlimited April 02, 2024 3 DC Adjustable Power Supply 0-50V 0-20 Ampere / Voltage and Current Adjustable Power Supply Planning a flexible DC variable power supply equipped for conveying up to 50V and 20A requires an integration of parts to guarantee solid quality. Welcome to this tutorial on designing a variable power supply with adjustable voltage and current using LM317 IC, BD139 and TP3055 transistors. But not a powerful DC voltage controller. This Adjustable DC power supplies are capable of delivering a variable output voltage or current. Locally adjustable power supplies can be adjusted through a built-in potentiometer, remotely adjustable power supplies can be adjusted . It comes with adjustable variable voltage and current features, completely customizable. The design uses dual 2N3055 transistors to handle the high current flow, while LM317 is used to regulate the output voltage. every DIY makers need this kind of bench power supply for making another project. May 13, 2022 · In this post I have explained how to make a simple variable power supply circuit using transistor 2N3055 and some other passive components. Jul 5, 2025 · What is SMPS SMPS stands for Switch-Mode-Power-Supply, which uses a high frequency ferrite based switching converter for converting the AC 220V to DC. Circuit Feb 20, 2020 · This article presents a simple power supply using an adjustable regulator LM350 that provides variable output up to 17V and maximum output current below 2A. With clean, stable output and real-time control, it ensures accurate, repeatable measurements in R&D, production, and educational labs. The use of a high frequency ferrite transformer makes the system highly efficient in terms of compactness, power loss, and cost.
