LED Display for Fuse protection
Being a fuse which protects the material used most often. Because of low prices may be used to protect expensive electronic circuit. In general, when fuse torn between us can know immediately. but sometimes torn fuses already we do not know. such as electricity automobile braking system, the system delays the electric current lot, so Fuse torn trouble we need to know immediately to security. I beg to advise the circuit is simple. It may demonstrate, seeing that now. Fuse already torn please. See illustration of the value of equipment that show that the note source voltage 12V, but if friends want to apply at V on the other. As a result exchange value of R1 and R2 can be obtained by calculating R1 = (Vin – 2) x 50 and R2 = (Vin – 2) x 10000 / 2.
