Buying Guide for Voltage Stabilizers

Some of the parameters that you should consider when purchasing a voltage stabilizer are listed below.

Rating

Check the power, current, and voltage rating that is given to the voltage stabilizer for selecting a unit that will best handle fluctuations and protect the appliance by supplying the same voltage input that it needs.

Always add a 20 to 25% safety margin while arriving at a number to purchase a voltage stabilizer.

Check the low and high voltage cutoff levels to get an idea about which stabilizer will protect your appliance best.

Applicability

Some voltage stabilizers are designed specifically for specific appliances like ACs, TVs, refrigerators, etc.

If you are looking for an appliance-specific voltage protection system, it is best to go for these sorts of devices.

Alternately, if you want protection for the house’s mainline, there are mainline voltage stabilizers with higher capacities explicitly designed to protect the main supply.

Indicator Type

Some voltage stabilizers have seven-segment displays, whereas others have LED indicators.

Depending on the kind of status updates you prefer regarding the incoming voltage, you can select either of these models for getting input regarding the voltage levels.

Time-Delay Systems

Not all but some voltage stabilizers feature an intelligent time delay system that protects the compressors present in some appliance.

Frequent restarts can damage the devices, and the presence of a time delay device will prevent this and add to the appliance’s longevity.

Mounting

Some voltage stabilizers are compact and can be mounted anywhere in the house. You can either affix them to the walls or place them on the floor.

Depending on the kind of installation you want and the attachment area available, pick a voltage stabilizer that you can accommodate easily.

Most are very compact, and therefore installation will not be an issue.

Some other factors that you may consider while purchasing a voltage stabilizer are additional safety features, brand, price, etc.

V-Guard and Monitor seem to be the most popular and reliable choices when it comes to voltage stabilizers.

 

FAQs

Can I use my AC voltage stabilizer for TV?

It is not recommended that you use your appliance-specific voltage stabilizer for other devices. These are rated differently and will work best with the appliance that they are designed to be used with. When used with other devices, the difference in the voltage cutoff levels or compatibility could damage your expensive device despite using a voltage stabilizer.

What features can I expect from a voltage stabilizer?

The exact features may vary from one model to the next, but all of them offer a high and low voltage cutoff, which will prevent the increased input from damaging the appliance. Some additional features include surge protection, thermal overload protection, circuit breaker protection, etc.

What is the purpose of the LED indicators on the voltage stabilizer?

There will be lights to indicate the incoming voltage levels, the output voltage levels, and whether the device is on/off. The instruction manual will list in detail what the blinking or turning on of individual lights means.

Why should I get a time delay voltage stabilizer?

Modern appliances like ACs, refrigerators, etc. have a compressor. With frequent disruptions in the power supply or frequent restarts, the compressor could breakdown. To prevent any damage to the appliances, the time delay function ensures it takes 4 to 5 seconds to restart the device and prevent unwanted damage while also extending its life.

Which voltage stabilizer should I purchase – copper or aluminum winding?

Copper is an excellent conductor, and voltage stabilizers with copper winding will prove to be energy efficient as well as more adept in handling the flow of current to the appliance. They are known to be more efficient and effective in maintaining adequate current levels by providing the path of least resistance.  

Summary

Voltage stabilizers are a very prudent investment to make, especially in areas with frequent power disruptions.

When you have spent so much money on expensive ACs, TVs, refrigerators, washing machines, etc., it is smart to spend a little more to ensure that they are protected in case of unprecedented fluctuations in the power supply.

In this article, we have summarized the features of the top ten voltage stabilizers in the Indian market spanning different functionalities and applications.

We have also included a short buying guide to help you with your purchase decision. So get a good voltage stabilizer and ensure a long life for your appliances!
