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!
