DIY 240W Bench Power Supply Tutorials 0V to 24V 0 to 10A

About: Nice to meet you my friends. Visit my Youtube Channel for get more instructable My youtube channel: https://www.youtube.com/c/longtechnical

Hi Guy.Today i will show you how to DIY 240W Bench Power Supply Tutorials 0V to 24V 0 to 10A with LCD voltage and current meter. This project attach the youtube video and schematic for you can understand what did i do for make it. Thanks you very much

Step 1: Watch This Video From Youtube

I make this video for you can easy understand what did i do for make this, in this video have some Advertising. Hope you like my video.

Step 2: Make the Schematic

This schematic i make from eagle software. The main IC is TL494 or( KA7500). You can download the file PDF of schematic here

Step 3: Make PCB by Upload Gerber File to the JLCPCB.COM

Go to https://jlcpcb.com/ for make PCB online

Only 2$ /10pcs for 2 layer PCB and Big Discount on First order Shipping https://jlcpcb.com/ Upload your gerber files and fill in Shipping Adress then click PAY.

Step 4: Received Your PCB After 2 Day

The PCB look great and so beauty

Step 5: Order the Component

List of part here:

You can buy it from any electrical store.

1 x TL494 ( KA7500)
1 x MUR 860 Diode

2 x 5.1kilo ohm resistor

1x 3.3 kilo ohm resistor

2 x 1 kilo ohm resistor

1 x 3v led

1 x 1000uf/50v capacitor

1 x 51 ohm resistor

1 x 100ohm resistor

3 x 1kilo ohm portentiometer

1 x 10 kilo ohm portentiometer

2 x 0.1 ohm 5w resistor

1 x 222 capacitor

1 x DB140 transistor

1 x MJE13009 transistor

1 x 680 ohm resistor

1 x inductor 300uh 10A

1 x big heat sink

Step 6: Solder PCB

Solder all component to PCB. We have the name on the top PCB. So this very easy

Step 7: Check Again.

Check all component were correct.

Step 8: Finish and Test Then Make the Cover Box

I connect with LCD current and voltage meter link here

Don't use that pcb... this instructable is clearly just an advertisement for their company. Instead use step down buck converters, an lcd multimeter module, and a computer power supply. Some other materials like a case, plugs, potientiometers, ect will be necessary but that is all super simple
