AC 230V over current & short circuit Protection.

Hi friends


In this Tutorial  i have made an AC 230V over current & short  circuit Protect.  You can use it with power supply or other device to limit the current. I have used very common components to make this circuit. Short circuit and high current protection circuit for AC 230V. If a PCB  is connected to AC 230V through fast Trip, the IGBT/MOSFET/capacitors etc in the PCB will not damage if there is an error in wiring/assembling. Fuse / MCB and other device cannot protect IGBT/MOSFET because these active components will fail before the fuse/MCB can protect it. So it is very important and powerful device.

      Connect the load and adjust the setting value of IC pin number 2 & 3 for over current and pin number 5 & 6 for short circuit. Finlay watch video show here. Thanks for stay with us.
