|| Tutorial: 12 Volt Transformer Output Check and 12 Volt DC Power Supply Connection.|| With video tutorial.

How are you all? I hope everyone is well and healthy by the grace of Allah. Today I will share with you 12 Volt Transformer Output and DC Power Supply.

I picked up two 12-volt transformers from an old junk shop for a very cheap price. And brought them home and checked the output with a multimeter using a 220-volt input voltage. In this post I will show you how to make a DC voltage power supply and its output, so let's get started.

First, you can see in front of me there are two old transformers, and on the right side of my hand, there is a digital multimeter, and I have collected these things to show you the AC output and DC output of the transformer with the help of a digital multimeter.

Then, to check the transformer, I applied 220 Volt input voltage, and you can see that I have shown you the primary output of 220 Volts before checking the secondary output of the transformer with the help of a digital multimeter.

Then you can see that I checked the output here by selecting the AC voltage range of the multimeter on a red and a black wire, and you can see that it is showing 15.62 AC output voltage here, and we will assume this as 12 volts.

Then I had another transformer; earlier I showed you two transformers, and this is a 12-0-12 3-ampere transformer. Now I checked the output; you can see that the AC output here is showing 12.83 volts as the output, which means the transformer is fine.

So how do we convert AC to DC and run the output and use our various 12-volt devices? Now I will show you how to complete the circuit with the help of a breadboard.

I have taken four IN4007 diodes here to make a bridge rectifier.

After installing the diodes, I am here with a capacitor of 16 volts and 1000 µF. If you want, you can use 25 volts and 1000 µF here; it is the safest.

Then I connected the line diode of the transformer, and after filtering through the capacitor, the output connection of DC 12 volts will come to our indicator line. Here I have connected a 1k resistance and a red light.

Then you can see that after I give 220 volts input voltage to the transformer, my circuit is complete, and here a red light is indicating, and inside my digital multimeter you can see the output is more than 12 volts, which is pure DC supply. When we run any load, its voltage will decrease.

Then I used a load to explain the matter better. Here I used a 12-volt LED light, and I turned on the output. You can see how beautifully the LED light is running.

In this way, by collecting old transformers from the market, I made a 12-volt AC to DC power supply, and I can use it for various purposes. If I want, I can make a power supply from 1 to 25 volts using step-down and -up modules.
