IC regulator protector circuit when load short
Today I have a little idea is the ICs regulator protector circuit in a load short-circuit. We design for the 12 volts DC regulator only. For example: IC-7812, or others 12V power supplies. How it works Figure 1 is the circuit diagram In the circuit, IC3-7812 as the 12 volts …
Simple electronic fuse circuit
The Fuse is a type of electrical equipment to the poor. Because it sacrifices itself. To protect the safety devices in the circuit. In the case of current flow in circuit too much. Until it melted. Due to an error in the circuit. Fuse sold in the market. Can be …
DC power supply protection circuits
The 3-pin regulator IC as a 78xx numbers have get very popular. I also like it because it is convenient and affordable. Although it is a short circuit within it. But very often, it would have been damaged when a short circuit. I think that should be a good short-circuit …
Use SCR help give fuse torn fast
If fuse slow get into trouble not good may make the circuit can is damaged. Normally fuse torn when current change too much. But more will torn must use the period of time which may late go to all right with regard to add SCR go to make fuse torn …
