Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings.
12v dc motor power supply circuit.
The bridge rectifier is 1 ic called gbpc5008 rated for 50a continuous and 800v peak.
It is an unregulated power supply because a load is dc motor only.
This ac adapter delivers dc of 12v 2a power supply circuit and is ideal for electronics projects.
These two 12v ac supplies are 180 degrees out of phase with each other thus making it easy to derive positive and negative 12 volt dc power supplies from them.
The power supply circuit designed in this project can be used for supplying power to led stripes and ropes.
It can also be used to feed supply to led boards.
12v dc power supply schematics.
The circuit is just a simple unregulated power supply.
The advantage of using a centre tapped transformer is we can get the both 12v and 12v dc supply using only one transformer.
Here are 4 simple 12v power supply circuits with output voltages around 12v.
First power supply circuit is built with bd139 one zener diode and a few passive components.
My son builds a simple first 12 volt power supply circuit for a 12v solar pump.
