Introduction: DIY 240W Bench Power Supply Tutorials 0V to 24V 0 to 10A
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
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
LongTechnical made it!
We have a be nice policy.
Please be positive and constructive.
where do i find the gerber file to upload to the pcb factory
i realy would like to do this project
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
