Best stabilizer for AC, Refrigerator or Home

You don’t need to go to the market to know the varieties of best stabilizers that are available today each providing different features based on different needs.

So, it is important for you to know which stabilizer will take care of your requirements. Based on thorough research we have shortlisted various parameters you must look into while buying a best voltage stabilizer for home.

How do I choose the right size of the stabilizer?

The first thing to do is to know the load that is connected to the stabilizer. After noting down the watts for all the appliances that will be connected to the stabilizer you will have to calculate the sum total power consumption to gauge the load that will be put on stabilizer. This will certainly determine the size and power capability of the stabilizer.

What should I look for when I am looking for a best stabilizer?

Various important factors such as input voltage range, overall power consumption and minimum and maximum input voltage should be looked into while buying a stabilizer. You must also look for features such as surge protection.

Do we get different single-phase and three-phase voltage stabilizers?

Yes, indeed we do. We make use of three-phase voltage stabilizer only for three phase motor voltage stabilization. For domestic purposes, appliances used at home a three phase motor will suffice.

What is the electricity consumption of voltage stabilizers for home?

Most of the products available in the market are 95 to 98% power efficient. This is to say they consume 2-5% of the maximum load.

Are modern appliances equipped with in-built voltage stabilizers?

Yes, most of the devices have in-built designed circuitry for power management. Some devices are deemed as stabilization free. But, it is important to be safe and check the required input voltage of the device and the input voltage you get in your house.

Buyer's Guide: How to Purchase Voltage Stabilizers

Voltage fluctuations are quite a common phenomenon of Indian households. We have all at some point experienced power failures and inconsistent voltage level disrupting our favourite electrical appliances. However, today we have moved far ahead thanks to the technological advancements that we can bid farewell to all those inconveniences.

Firstly, we must understand how they actually affect the appliances.  When the voltage level drops down, the current increases which can really harm the appliances to the point of rendering them useless. Hence, a well-working voltage stabilizer has become a strong necessity today to guarantee an uninterrupted daily life.

So, with myriads of options available in the market with tons of different kinds of voltage stabilizers for different purposes you can easily end up getting confused and buy the one that is not suitable for your house.

For this purpose we have crafted this guide on the basis of thorough research laying down pointers talking why does voltage fluctuation occur and also about the most important factors you must look for in a voltage stabilizer.

Frequently Ask Questions

1. What should my voltage stabilizer be equipped with?

  • Strong mounting: As these stabilizers involve working with high amount of power it is safe to mount them at a considerable height to prevent people to get electric shocks.
  • Precise indicators: Your voltage stabilizer must be equipped with a fairly revealing  digital indicators to keep you updated on the voltage level.
  • Time delay system: Time delay system is of huge importance as it is responsible for creating time lapse which helps the compressor generate the optimum required voltage and on the basis of that balance the current flow.
  • Digital technology: The digitalization of technology has helped a lot in allowing the voltage stabilizers to adapt with almost all of the appliances that are available today.

2. How do voltage stabilizers fix voltage fluctuation?

The name aptly describes compensation of voltage fluctuation.  Basically, if the input voltage wavers off inconsistently then the voltage stabilizer will regulate and compensate the highs and lows to ensure consistent regulated voltage output.

3. How to decide the right sized best voltage stabilizer for home?

First thing you must note down all the appliances which you will be connecting to the stabilizer. After that, calculate the sum total of the power consumption to get the figure of the total power that will be fed to the stabilizer. These are important figures that will give you a clear outline of the requirement of the voltage stabilizer. Most of the stabilizers available in the market today are denoted with VA or kVA rating. To arrive at actual VA rating, you must increase the watts with 20% to get an approximate number. For instance, if the watts sum of the load that will be connected to your stabilizer is 1000W then you must simply opt for 1200 kVA.

4. Important factors that I must consider?

Before you set out to buy a voltage stabilizer you must make a careful note of the input voltage range of power you get at home. Based on this figure you can choose a stabilizer because each device comes with a specific range of voltage which it can regulate. So, this will considerably narrow down the device search for you. You must make sure that the device is equipped with thermal overload protection to protect your devices from getting harmed due to excessive heating. Also, surge protection and Advanced IC design technology are 2 important parameters because it makes your stabilizer very sensitive to slightest of fluctuations so that your appliances will be prevented from sudden increase in the input voltage.

5. Are there different single-phase and three-phase voltage stabilizers available in the market?

The requirement of three-phase voltage stabilizer is only limited to places where three phase motors are used. Mainly in industries where we find a full three-phase setup three-phase voltage stabilizers are used. All the basic appliances at home make use of single-phase voltage stabilizers. So, it is safe to say that three-phase voltage stabilizers are not used for residential purposes. It is essential to understand that you do not make use of voltage stabilizer for your entire house as these devices consume power too. So, it is much more feasible to make use of stabilizers for individual appliances.

6. How can I cut down on my bills including the voltage stabilizer usage?

Logically, the power efficiency depends upon the performance of the stabilizer. Ideally, they deliver 95-98% efficiency so they consume around 2-5% of the power. If we see it in detail, with 1 kVA stabilize you will consume 50 watt power. So, if you utilize it for 10 hours straight it will make use of 0.5 units of electricity. So, naturally excessive use of it can only increase the consumption. Hence, it is the wisest choice to make use of stabilizer for individual devices.

7. Do we get modern refrigerators, AC, TV with in-built voltage stabilization?

Today, most asked question is that how to choose stabilizer for refrigerator , AC , TV with in-built voltage stabilization? So, as most of the appliances we get in the market have some sort of internal circuitry dedicated to power management.  Most of the TVs, and computers can run even on low voltages. However, stabilizers provide additional security from not only voltage fluctuations but also from surges which can completely harm your appliances. Appliances like AC, washing machines do require a voltage stabilizer as very few appliances can actually run on high voltage.
