Kısa devre (Aşırı akım ) koruması devresi 50 Volt ve 49 Ampere kadar çalışabilir full detaylı

Hi, I used an irfz44n and a pc817 optocoupler to create short circuit protection by taking advantage of the coil's inductive properties. Material quality is crucial. Try it 100 times and then plug it into your system. If it doesn't work or burns out, it's your responsibility. I'm using it in my power supply. When unloaded or after a short circuit, it loses voltage for a while, or it fluctuates by reducing the voltage slightly. It fixes itself when I reset it. There's no problem while using it. However, it's still stuck in my system because it acts as a short circuit very quickly. ***Note: If you're using it in a power supply, you can connect a resistor in series between the coil and the optocoupler to protect it from working when drawing high current, not low. You can try 470 ohms with 1k or 2.2kΩ, and add the appropriate resistor. 1 irfz44N MOSFET 1 pc817 optocoupler 1 coil (size not crucial) 1 push button
