Understanding AVR Fuses

Meiji AVR 500WAutomatic Voltage Regulators or AVRs are our good friends at home and even in our offices. They protect our home appliances and different equipments from inconsistent levels of electricity flow that could damage them. During times when electricity fluctuates, it stops this equipment from being damaged through regulating its working voltage and therefore maintaining a consistent flow or load. AVRs are very helpful for certain home equipment that is sensitive from inconsistent electricity flow.

But of course, even these AVRs are in danger sometimes. When electricity surges too much orAutomatic Voltage Regulator when a particular user makes a mistake on the voltage setting, there is still the possibility of failures that may affect these AVRs. The AVR itself may break down, too. And that may lead to some serious damage, not just in the AVR itself but also in our appliances.

This is why the availability of fuse in some AVRs is beneficial. Meiji servo-motor type AVR includes a fuse that helps protect the AVR unit. In Meiji AVRs, the fuse blows when there is overloading due to either miscalculations of the users in terms of the wattage and/or other factors. So, even when there are some errors on the settings, the AVR itself would not be harmed as a whole. Instead, only the fuse will break down, hinting that something has been wrong.

Therefore, the fuse fulfills its role as a resistor. It serves more of as a sacrificial device. At first, it tries to interrupt excessive flow of current to the system to avoid damage. So, as much as possible, it allows only the normal current. But if it reaches the maximum amount of current it can handle, it automatically melts down and disconnects. And because of this, the flow of electricity to the equipment of home appliance is interrupted as well and thus avoids incidents of overheating, damages and even fires.

Automatic Voltage RegulatorsAnd since only the fuse breaks down in times of error, it means that you can still make your AVR work even if the fuse has already gone bad. All you have to do is turn the AVR off and take out the broken fuse. For most fuse type AVRs, the fuse can easily be found as it is usually attached on the external of the AVR itself. It is also very easy to detach. Then, you have to get a new one from any nearby hardware store and just replace the old one. This way, the AVR can still work as though it were new. And whenever something wrong happens, you just have to replace the fuse.

Indeed, the AVR fuse saves AVRs from serious damages. It is also a practical choice since you no longer have to get a new MEIJI AVR whenever failures occur. As long as you replace the fuse, your MEIJI AVR can still work well. Talk about efficiency!
