How to make 24v adapter or DC power supply easy at home

In this project we learn how to make 24v adapter or dc power supply easy at home using few simple steps with the help of circuit diagram. its very simple useful and homemade project. if you follow these steps then you can easily build your own 24v power supply.

how to make 24v DC power supply

for making this project we need some components.

Components for making 24v adapter:

12-0-12 or 24V 1 Amp Transformer
LM7824 Voltage regulator
Heat sink
50v 1000uf capacitor
1N4007 Diode (4)
LED
1K 1/4W Resistor
PCB Board
Soldering wire
Soldering iron

Circuit Diagram of how to 24v dc power supply:

24v power supply circuit diagram

Transformer has 2 side. one side is use for input and 2nd side is use for output.
input side of transformer connect with 220v direct power.

Diode bridge circuit diagram

How to make diode bridge:

Take a 4 diodes of 1N4007.

1: 1st diode head connect with 2nd diode tail
2: and 2nd diode head connect with 3rd diode head.
3: and 3rd diode tail connect with 4th diode head.
4: and 4th diode tail connect with 1st diode tail

Output side of transformer connect with diode bridge.

1 wire connect between 1 and 2 number
2nd wire connect between 3 and 4 number.

Now connect 50v, 1000uf capacitor with diode bridge.

1: positive side of capacitor connect between 2 and 3 number pin.
2: negative side connect between 1 and 4 number pin.

Now connect 1k resistor and LED with positive and negative wire.
Now take LM7824 Voltage regulator.

LM7824 pinout diagram

LM7824 has 3 pin.

1: 1st is use for input
2: 2nd pin is use for ground
3: 3rd is use for output

Now 1st pin of voltage regulator connect with positive side of capacitor. or positive side of wire.
2nd pin of voltage regulator connect with ground wire. or negative side of capacitor.
3rd pin of voltage regulator is provide you 24v positive power
and 2nd pin of voltage regulator is use for negative power or ground wire. like diagram.

these are few steps if you follow properly then you easily make LM7824 power supply circuit. we learn it more battery with watching video.
