Tutorial: Converting a 220 volt AC to DC charger fan to 12 volt DC. || With a video tutorial.

How are you all? I hope everyone is well and healthy by the grace of Allah. Today I will share with you how to convert a 220-volt AC to DC charger fan to 12-volt DC only.

A few days ago, a brother from my area gave me an AC to DC 220-volt charger fan and said that he is not going to use this fan and he bought a 12-volt power supply and battery and asked me if he can run this fan with a battery, so I told him yes, I can convert it to 12 volts, and I have converted this fan to 12 volts, so let's see step by step how I modified it beautifully.

Step -01

Now the charger fan that you see on my work table is a 220-volt-powered AC to DC charger fan. Now it will not run through 220-volt current but through 12-volt solar and battery, so let's see how to convert it later.

Step -02

In front of the fan, you can see a 12-volt voltage regulator in my hand; it is mainly used to control the speed of the motor. You cannot use it to control the voltage, only to control the motor, and I have a post about it in the past; if you want, you can see the tutorial, and through it I will change the fan today.

Step -03

In this picture, you can see a connection jack in my hand; it is basically known as a male-to-female jack, and one jack will be installed inside the fan and another jack will be installed with the input voltage.

Step -04

Now you can see that I have removed the body cover of the fan, and I will remove the internal circuit and the transformer because I will not need these two things anymore, and I will keep the battery here so that the fan can stand on one side so that it does not fall off.

Step -05

Now you can see that I have disconnected the motor line from the circuit. Here are two wires in my hand. You can see these two wires are my motor lines. So the reason I am separating it from the circuit is that I will connect the voltage regulator line to it, and I will remove the old circuit of the fan, which was the controlling circuit.

Step -06

Now you can see the main points of this work. On one side I have placed the battery inside the cover, which will control whether the fan stands, and on the other side you can see I have taken the motor wire and taken the voltage regulator and taken the male-to-female jack. With these three connections, my fan will now run on a 12-volt DC connection only.

Step -07

Now you can see that I have connected the two wires of the motor to the output line of the voltage regulator. The two lines on the left side of the power supply that I am holding are the positive and negative outputs.

Step -08

Now you can see from this picture that I have also connected the male-to-female jack, given an input voltage connection and an output voltage connection. Here you will see that all four connections of the voltage regulator are connected to the male jack, but I have given all the input and output connections.

Step -09

Then you can see that I have given the input voltage from the power supply to the male jack, and the female jack goes to the voltage regulator, and from there the voltage is controlled and goes to my fan, and the voltage regulator is going to indicate a red light, and it is now moving.

Step -10

Now you can see the output connections that show how the fan is moving, and the variable regulator in the voltage regulator can be reduced or increased to control the motor, and you can feel the wind as you wish.

Step -11

Now you can see that I have modified the voltage regulator where the old controlling circuit is, and the one that I have replaced will have to be used to provide input voltage, and you can understand it better by watching the video below to see it more beautifully.

Step -12

So now the complete body cover of my fan is fitted, and you can see that the fan is standing, and I have placed the battery below; otherwise, the fan would have fallen to one side, and I have checked the input and output voltage regulator, and everything is fine. The owner of this fan can now use this fan from a 12-volt solar, 12-volt battery or 12-volt power supply if we do not have electricity. Let me know how it was today.
