2 DC power supply protection circuits
The 3-pin regulator 7800 series get very popular. I also like it. Because it is convenient and affordable. Although inside it has short circuit protection. But often, it would have…
Simple Overload protection circuits
This is overload protection for transformers and load, is simple circuit cut off-on by relay. And so fast switch witch SCR driver. can set sensitive by VR1
Blown Fuse indicator circuit with LED Display
This is Blown Fuse indicator circuit by LED Display. A Fuse be the equipment protects that use often most. Because of cheapness can use protect electronics
How to make super fast fuse using SCR
To make super fast fuse using SCR. Why uses it? If fuse works slowly. So the circuit may damage. This fuse works so fast. Your circuit will be safe!
Simple electronic fuse circuit
It can be used to replace conventional fuses. Because it's comfortable not need to replace the fuse every time the power too over. This circuit use transistors so simple and low cost.
