0-30V 3A Adjustable DC Supply
This is cheap adjustable 0-30V 3A Laboratory DC Power Supply circuit. It is high efficiency regulator circuit by using IC regulator UA723 and TIP3055 as power transistor so easy to install. It is designed to protect over current load maximum 3A Technical data -Need to use transformer : 12-0-12V 4A. …
Simple 12V 2A DC power supply
Today, my son builds a simple 12V 2A DC power supply for a 12V solar pump. It is an Unregulated power supply because load is DC motor only. Note: More circuits 12V Power Supply How to works I teach son to understand the working principle of this projects. The main …
Ham radio power supply circuit with RFI elimination
This is the Ham radio power supply circuit with RFI elimination for Amateur radio. A typically Radio transmitters use High-frequency transistors as current driver so can cause very severe electromagnetic. Therefore, The power supply must be able to make the current higher than 10A. Figure 1 the schematic diagram RFI elimination …
