Its 2015! You probably have new appliances now in your home? Whether they’re for entertainment or kitchen use, remember to use an Automatic Voltage Regulator (AVR) to it.

Some people might think, “No need!” while others believe that it depends on the area you live in. And if your city does not have voltage problems, you can connect it directly to the plug. These might be true but being knowledgeable of the facts can be safer than believing the opinions of others.

What are Power Surges?

According to Tom Harris, a contributor on the blog site “How Stuff Works”, power surges occur when something boosts the electrical charge at some point in the power lines. This causes an increase in the electrical potential energy, which can increase the current flowing to your wall outlet. A number of different things can cause this to happen.

Power surges are also cause by the operation of high-power electrical devices, such as elevators, air conditioners and refrigerators. These high-powered pieces of equipment require a lot of energy to switch on and turn off components like compressors and motors. This switching creates sudden, brief demands for power, which upset the steady voltage flow in the electrical system. While these surges are nowhere near the intensity of a lightning surge, they can be severe enough to damage components, immediately or gradually, and they occur regularly in most 31033351b__62919_stdhomes and building’s electrical systems.

Meiji AVRs can surely help you from such power surges. Meiji AVRs are designed to stabilize voltage increase and even decrease. Not only that! If your device came from abroad, and has 110 volts requirements, Meiji AVRs has a built-in 110 volts output socket. Meiji AVRs are available from 500 VA to 10 KVA ratings, just right for your new home appliances.

In today’s system of electricity distribution, power surges are an unavoidable occurrence especially in the Philippines. So be sure to use Meiji AVRs to protect your new appliances. Surely, you would never want them to be destroyed easily.

Through the advancement of technologies and continuous upgrade of mechanical devices and appliances, it is recommended to associate them with the right kind of Automatic Voltage Regulators (AVRs)

 

As some of us know, AVRs have one purpose, and that is to maintain the voltage supply at a constant “range”. AVRs come in two main types: Servo-motor type and “step” type.
Servo-motor type AVRs has a coil of wire and a mechanical motor which rotates in the coil to keep the output voltage at a certain value. They are usually larger and heavier. These kinds of AVRs have power-on delays which result to a more accurate voltage output.
Step types AVRs are usually cheaper. They contain a set of relays or transistors which keeps the output voltage in a certain range of value. Example of the steps might be: 160-180, 180-200, 200-220, 220-240, and 240-260 volts. Each of these ranges is being controlled by a transistor or relay inside. So if you hear a click on a relay type AVR, it means it is switching from one voltage range to the next up or down range. It is not as accurate in voltage output.

So which is better?

Servo-motor type AVRs are better especially if you live in an area where the voltage fluctuates a lot. The more accurate voltage the AVR emits, the more protection it gives to your treasured appliances.

Meiji Electric offers you the best Servo-motor type AVRs!AVR 500

Meiji Servo-Motor AVRs

Using Meiji AVRs is the best solution in keeping the voltage supply at a constant range for your appliance, with or without voltage fluctuations or imbalance. Meiji AVRs are servo-motor type AVRs, designed to be distortion less and provide an accurate voltage output. From 500 to 10, 000 VA capacity, it can accommodate both low and high rated appliances. It saves your treasured appliances & processes from damaging effects of fluctuations. This way, you can focus on things that matter to you.

In addition, Meiji AVRs have a converter, from 220V to 110V for 110V-appliances like those which are imported. Now, you don’t have to buy a separate transformer for them.

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.

AVRs are in danger sometimes

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.

Fuses in some AVRs is beneficial

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.

Make your AVR work even if the fuse has already gone bad

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!
