12v Battery Charger|How to make 12v Battery Charger|Transformerless Power Supply
Today i'm going to show you How to Make 12v Battery Charge
With this charge you can charge any type of 12 v battery even your car battery
It is very necessary in cold days because the battery drains out very quickly. Laptop charger
Dc to Dc Step Down Converter
It's will convert 19 volts from your charger to 14 volts to charge the battery
It'll provide constant voltage and constant current. (very necessary)
It comes with 3 LED indicators (red, blue and green) red show constant current blue show load and green show constant voltage "full charge"
Features
Input voltage range:6-38 VDC (Note: input voltage not exceeding 38V)
Output voltage range:1.25-36VDC adjustable
Output current: 0-5A
Output power: 75W
High efficiency up to 96%
Built in thermal shutdown function
Built in current limit function
Built in output short protection function
Follow the steps
Cut down the jack of the adapter
Remove the outer shield with a blade (Carefully)
You'll see 2 wire red and black, black is negative and red is positive
You can see the label over the board
The red wire of adapter will go to “IN+” positive of the board (see the image)
The black wire of the adapter will go to “IN-” negative of the board
Tight the screw terminal with a screw driver
Now connect alligator clip
Red alligator clip wire will go to "OUT+" Positive of the Board (see the image)
Black alligator clip wire will go to “OUT-” Negative of the Board
Now you need a multi-meter to set it up
Plug the power to the adapter
Connect the black alligator clip to negative lead of multimeter and red alligator clip to positive lead
you can see 2 Potentiometer over the board (see the image)
The first one is voltage and the second one is current
Now select the DC voltage reading on your multi-meter and turn the Potentiometer with a screw driver until you get 14 volts reading on the multi-meter
Now select the Current Reading on your multi-meter and turn the second Potentiometer with a screw driver until you get 2 amps reading on the multi-meter (you can go up to 5 amps all it depends upon the battery capacity if you have a bigger battery "like a car battery you can go up to 5 amps"
