12v 3a regulated power supply circuit diagram. 12v and 5v output many ideas of 12v and 5v dual power supply circuit diagram at 3a max. This circuit is based on ic lm7812 it is a 3 terminal ve voltage regulator ic. For most of our sensors and motors we use voltage levels like 3 3v 5v or 12v. Many years ago i built a first variable power supply using lm317.
Here are 4 simple 12v power supply circuits with output voltages around 12v. But motors like servo motors or pmdc motors which run on 12v or more require a high current. Second the output current up to 3a. First power supply circuit is built with bd139 one zener diode and a few passive components.
12v dc power supply schematics. Now i have still used it. 24v 2a power supply circuit. Third adjust the output voltage of 1 25v to 20v.
It has short circuit protection thermal overload protection. First it is a high quality power supply. So we are building here the regulated power supply of 3a current with the variable voltage between 0 to 24v. It is very difficult to find that type of regulated ics which deliver that high current so this circuit will work on the places where.
1 5v 3v adapter usb to 1 5v or 3v converter circuit small uninterruptible ups. But if you need to use a 3a adjustable voltage regulator. Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings. This below circuit is suitable for you with 5 important reasons.
This is a schematic of a simple dc 12v 3a power supply circuit using 2n3055 transistor. 12v 1a linear regulator using transistor and zener diode.
Here This Circuit Diagram Is For 12v Regulated Fixed Voltage Dc Power Supply These Power Supply C Power Supply Circuit Circuit Diagram Power Supply Design
