12VDC Electronic Fuse Circuit

12VDC Electronic Fuse Circuit

In electronics and electrical engineering a fuse is a type of more protection devices. Its essential component is a metal wire or strip that melts PLS current flows too, which breaks the circuit that is connected, thus protecting the other components of the circuit from damage caused by excess current.

circuit diagrams in the upstairs lounge is an electronic fuse that protects against short circuit load voltage of 12 VDC. You can adjust the flow using a 10K pot. If the fuse is used with very high currents, the lower the resistance value 0.1/5W, the value of watts of resistance must also increase

Note:

• IC1 can use any of the op-amp IC (eg OA 741).
• IC2 can use any SR latch flip-flop (eg 54HC279).
• Use a 12V relay and currents that are customized to your needs.
