Best Voltage Stabilizers in India Reviews & Buying Guide 2020

Voltage fluctuations are quite common in India. They can cause harm to most of the electrical appliances at your home such as the fridge, television, air conditioner, etc. Sometimes, they can even damage the appliance permanently.

Selecting the right kind of stabilizer for the electrical appliances at your home can help you get rid of this problem. A good stabilizer prevents unwanted voltage fluctuations from entering into the electrical appliances, making the operation hassle-free.

There are two main factors that you should consider before buying a voltage stabilizer. They are:

Stabilizer Working Range:

Each stabilizer comes with a minimum and a maximum input voltage to which it can stabilize the output voltage. For example, let’s say that the input voltage range of a voltage stabilizer is 150 V (min) –250 V (max). Now, if the voltage in your house either goes below 150 V or above 260 V, the stabilizer will cut off the electric power supply to the appliance.

However, if the voltage is within the working range i.e. if it is either 170 V or 200 V, then the stabilizer will try to stabilize it to provide a desired output voltage range.

Stabilizer Type:

The voltage stabilizers are designed on the basis of the appliance that you are going to use it with. You cannot just pick a stabilizer and use it with any device. The different types of stabilizers available in the market are:

  • Stabilizer for refrigerator of different capacities
  • Stabilizers for AC
  • Stabilizers for washing machines, microwaves, etc.
  • Digital stabilizers for TV, music system, etc.

To help you buy the best stabilizer, we have shortlisted 10 best voltage stabilizers for TV, AC, Refrigerator, and Washing Machine. We have shortlisted them on the basis of brand quality, customer reviews, and different requirements of the customers.

To help you understand the factors that play a major role in deciding its effectiveness, we have included a buying guide at the end of the article.

Things to Consider Before Buying a Voltage Stabilizer

You cannot just let your new electrical appliances get damaged due to constant voltage fluctuations. Hence, buying a voltage stabilizer is a must and these factors will help you decide which stabilizer is the best for your appliances.

1. Stabilizer Working Range:

Before buying a voltage stabilizer for your home, it is very important for you to make a note of the input voltage range that you get at your place. Generally, you get an input of 230 V in India.

Also, check the range of the voltage stabilizer. If you are buying a stabilizer with a range of 150 V to 260 V, the stabilizer will automatically turn off the supply of current when the voltage either goes below 150 V or above 260 V. It will prevent the current from passing to the appliance in such scenarios.

However, if the voltage is within the working range i.e. between 160 V and 250 V, the stabilizer will start working on stabilizing the input voltage and set it accordingly to the desired range of output.

If you wish to connect more than one appliance to a stabilizer, it will be better if you buy a mainline stabilizer. This type of stabilizer is installed between the main power supply of your home and other appliances. It is designed to smoothen out the voltage fluctuations coming from the main power supply to provide a constant electric supply to all the devices. To read more about the mainline stabilizers, check this article.

2. Surge Protection:

You should always buy a voltage stabilizer that offers surge protection or spike guards. Whenever there is a short-circuit issue due to lightning or thundering, the voltage can fluctuate a lot.

During such conditions, the surge protection feature directly turns off the supply of current immediately to all the devices that are connected to the stabilizer. This ensures that none of the appliances are getting damaged.

3. Mounting:

As the voltage stabilizer works using electric power, there is always a risk of the stabilizer getting wet or damaged when you place it on the ground or somewhere unsafe.

Thus, most of the brands allow you to wall-mount the stabilizer so that you can place it at a safe and higher level. It not only protects the stabilizer from damage but also protects your family from the risk of electric shocks, especially if you have children at your home.

4. Indicators:

The modern voltage stabilizers come with special LED indicators that display the input and the output voltage. It also helps you in keeping a track of the voltage fluctuation levels and the performance of the appliances and the stabilizer. Almost every stabilizer that we have mentioned in our list comes with an indicator.

In earlier models, you would find the galvanometer-type indicators where you will have to understand the readings by carefully watching the movement of the arrows on the indicators.

5. Time Delay Systems:

Compressor locks up if it is interrupted by a short term or monetary power outage (for less than 10-15 seconds). In this condition, the motor consumes strong current. The compressor turns very hot due to this. When the over temperature protection system shuts down the power supply, it can lead to the tripping of the compressor too.

This problem can be solved using Power on Delay feature in voltage stabilizers.

As this power outage disturbs the functioning of the compressor, the Power on Delay function waits for the completion of Time Delay. Until then, it does not turn on the compressor again. This helps the compressor in coming out of this lock period.

6. Digitized:

Most of the brands are focusing on digitizing the voltage stabilizer to make it more reliable and accurate. These modern and digitized models work fine with most of the devices.

All you will have to do is shift the stabilizer from one appliance to the other and let it work. Some of these models can be even connected to the generators too.

7. Overload Protection:

Whenever there is short-circuit or current overload, the overload protection feature helps in turning off the output of the stabilizer completely.

8. Warranty:

Most of the brands offer a warranty period of 3-5 years on the voltage stabilizers to provide enough protection to the appliances at your home. Always make sure that you are buying a stabilizer that is engineered specially for the appliances at your home.

How do Voltage Stabilizers Protect Your Electrical Appliances?

Stabilizers are also called as Automatic & Safe Voltage Regulators. These are static devices that work on stabilizing the input voltage before passing it to the appliances directly.

A stabilizer identifies the voltage fluctuations beforehand and then regulates it in order to provide a uniform range of output voltage to the appliances.

If the utility voltage is low, the stabilizer figures it out and boosts it until it reaches the required level and then feeds it to the connected device to promote a hassle-free operation. When the voltage is high, it cuts off the voltage until it reaches the limit and then let it pass through the device.

The stabilizers perform this task using an electronic system that modifies the required taps of the in-built auto-transformer using high-quality electromagnetic relays in order to produce the desired voltage. Also, if the required voltage is not in the range, the required transformer tap is switched using a mechanism that brings the voltage supply in a safe range.

Thus, the stabilizer here functions as a safeguard between the utility and your appliances by constantly observing and stabilizing the voltage fluctuations continuously that appear in the utility. This process makes sure that the electric appliances at your home receive a consistent and stable range of voltage as required for a lag-free or hassle-free operation. It also increases the operational life of the devices.

Can Voltage Fluctuations Harm The Electrical Appliances At Your Home?

In India, the ideal input voltage in the home electric circuit ranges between 220 and 230 V AC (Alternating Current). Whenever the input voltage drops below 220 V or rises above 230 V, this is referred to as voltage fluctuation.

Circuit breakers are designed to protect the electrical circuits from any damage caused due to current overload or short circuit. Hence, you will notice that almost all the home circuits come with pre-installed circuit breakers. Due to this, in case of voltage fluctuations, the circuit trips off automatically and prevents the appliance from getting damaged.

When the current supply is restored, there are slight chances of surge in voltage. This surge often leads to damaging of appliance.

Thus, circuit breaker is very important as the appliances can get damaged due to low voltage. This is more applicable to the appliances that work using motor or compressors.

To deal with this issue, you must install a voltage stabilizer. Doing so ensures that the current first passes through the stabilizer and is then feed to the appliance.

What Causes Voltage Fluctuations in the House?

Voltage fluctuations are caused due to multiple reasons. One of the main reasons behind it is the fluctuation in the input supply from the main grid.

Inadequate earthing or bad wiring can also lead to voltage fluctuations. Sometimes, voltage fluctuation is also caused due to a short circuit.

In some cases, voltage fluctuation occurs whenever you switch on a high-powered appliance suddenly. Some of those appliances are electric motors, pump sets, or AC.

Overloading can also cause voltage fluctuations.

Frequently Asked Questions

1. Are there different stabilizers available for different types of appliances?

All the voltage stabilizers are engineered optimally depending on the appliance that you are going to use it with. These stabilizers are distinguished on the basis of the energy limit along with the features of a particular electric appliance.
Each appliance has a certain energy limit and keeping these limits and restrictions in mind, the stabilizers are engineered accordingly. Different types of stabilizers *available in the market are:
*Stabilizers for refrigerators
*Stabilizers for air conditioners
*Stabilizers for washing machine, microwave oven, treadmill
*Digital stabilizer (for LED/LCD TV, music systems)
*Stabilizers for CRT TV
*Mainline Stabilizers

2. Are there different stabilizers for single-phase and three-phase?

Yes, there are. However, a three-phase voltage stabilizer is used only when the voltage stabilization is required for a three-phase motor or while stabilizing voltage for a full three-phase set up.
All the appliances that we use at home can work on a single-phase voltage stabilizer only. You might not need a three-phase voltage stabilizer until you are trying to stabilize the voltage of the entire house on a three-phase connection.
It is generally not recommended to put a stabilizer for the entire house as the voltage stabilizers also use electricity to work. Thus, if you are using it for the entire house, the stabilizer will consume electricity throughout the day. On the other hand, if you are using the stabilizer only for a particular device, you can switch off the stabilizer whenever you are not using the appliance.

3. Do the recent or modern models of ACs or refrigerators come with an in-built voltage stabilizer?

Most of the modern appliances like fridge and AC come with a bigger voltage range for hassle-free operation. This means that if the earlier models of the fridge worked between 200-240 V range, the latest models offer a bigger range of 170-290 V.
Thus, the refrigerators come with in-built low and high voltage cut-off but they don’t come with in-built voltage stabilizers. Using a voltage stabilizer might not be that important unless the voltage in your area shoots up or down beyond or below the limits constantly.

4. Do you need a stabilizer for a refrigerator?

Most of the modern models of refrigerators are engineered to handle large voltage range. As they use SMPS (Switch Mode Power Supply), they can work between the range of 110 V and 290 V.
You must check the power specifications of the refrigerator before buying a stabilizer for it. If the offered voltage range is large, you might not need a stabilizer at all. However, if the voltage range is low, then you should use a stabilizer. The earlier models of refrigerators need a stabilizer as they can get damaged due to electric surges (especially the ones that come with an inverter technology). Thus, you should either buy a stabilizer for the fridge that comes with a surge protection feature or buy a surge protector separately along with the stabilizer.

5. What is the electricity consumption of voltage stabilizers?

The electricity consumption of the voltage stabilizers depends majorly on its efficiency. Most of them are 95-98% efficient. This means the stabilizers consume around 2-5% of the maximum load.
So, if you own a 1kVA (or 1,000 VA) stabilizer, it will consume around 50 W on peak load. This means that if a 1 kVA stabilizer is working continuously for 10 hours, it will consume around 0.5 units of electricity. If you let it stay on for the whole day, it might consume a lot of electricity.
Hence, it is recommended to use a voltage stabilizer for a particular appliance than using a mainline stabilizer. If you use a mainline stabilizer, you will have to keep it turned on for the entire day throughout the year and it can have a huge impact on the electricity bill.

6. What do you mean by a step-up and step-down stabilizer?

The most important job of a stabilizer is to ensure that the output current is in the acceptable range of 220 V to 240 V. If the input voltage is less than 220 V, the stabilizer will increase the output voltage to reach a minimum level of 220 V. In this case, you term it as a step-up voltage stabilizer.
However, if the input voltage is too high than the standard range, the stabilizer will reduce the voltage to maintain the required limits. Here, the device acts as a step-down stabilizer.

7. What is the difference between a voltage stabilizer and an inverter?

An inverter converts DC into AC and allows the electrical appliances to work even when there is no power. The inverters come with a battery that lets you store electricity. This electricity is then used whenever there is a power cut. A voltage stabilizer, on the other hand, does not function like this.
The main responsibility of a voltage stabilizer is to stabilize the input current and make sure that the appliance that is connected to it receives electricity within the prescribed voltage range i.e. 230 V. If there is a power cut or outage, the stabilizer will also stop working.

8. Why do we still use UPS for computers rather than using voltage stabilizers?

Even though the voltage stabilizer can stabilize the output voltage, it cannot store electricity and power up an appliance in case of a power outage. Whenever there is a power cut, the computers need some time to save the ongoing works and then shut down without losing any data.
The UPS helps the computer in finishing these activities by providing the electricity supply even after the power cut.

9. Can the same stabilizer be used for AC as well as other appliances?

No! If you have a traditional rather regular stabilizer, you must not use it for AC as they both are not compatible with each other. An Air conditioner is in requirement of additional safety and hence, you need some additional built-in features to ensure both your stabilizer and the Air conditioning is safe. The additional features include, time-delay system often referred to as ITDS which makes sure the compressor of the AC has all the time for safety.

10. Will stabilizers save on electricity bills?

Such terms and conditions do not come with these devices; this is because stabilizer is no power saving unit or output. You can though expect saving up to an extent this is because the basic job of a stabilizer is to keep the power consumption stable and there are chances that some of the power may be saved in between the process. You may assume the stabilizer actually consumes its own fraction of power. The basic power wastage of a stabilizer is up to 5% in maximum, but if you use it on an excessive basis you may end up wasting up a lot more energy.

11. Do LED TVs need voltage stabilizer?

This purely depends on your perception of safety but if you ask for advice, the modern LED TVs do not necessarily need a voltage stabilizer in order to work. The reason for this is that TVs have the capability of working for a Voltage between 110 V and 290V. This is the reason why any of the fluctuations in the electricity would not affect the TV.
But there are some cases where the TV may get damaged, such as power surges and sudden spike in electric current. This is when you need a surge protector to save your TV, from such a sudden spike in electricity. In such a case you may choose to buy a stabilizer with a feature called surge protection.

12. What are some of the effects of voltage fluctuations?

You basically need a stabilizer when there is a lot of fluctuation in the voltage. You may notice a constant pattern of high and low fluctuations or may notice it all in a sudden especially after power cuts. But what stays constant is that your appliances will be prone to damage. The basic reasons for such fluctuations are bad wiring, overload, suddenly switching on or off high voltage devices, bad earthing or even short circuits.

13. Is there only one phased stabilizer?

There are different kinds of stabilizers as in different phased stabilizers. You will come across a one phased stabilizer and also a three-phased stabilizer. If you are in seek of residential use then a one phased stabilizer would suffice for your need. But in case you are looking to stabilize an entire house or a three-phase connection you are will need a three-phased connection. You need to dig deeper if you wish to know each and every aspect of the phase connections but hitting the web.

Conclusion

So, as you can see you need to have a basic understanding of few things before you can buy a stabilizer for your appliances. A stabilizer for AC can’t work on a refrigerator and vice-versa. Also, you need to know certain parameters like power consumption and voltage fluctuation etc to purchase the right one that can take the load of the appliance and even the input voltage.

Nevertheless, our top recommendation for ACs is the V-Guard VWI 400 Voltage Stabilizer for Inverter AC for TVs is the V-Guard Voltage Stabilizer for TV and for other appliances like refrigerators etc, it is the V-Guard VGSD 50 Voltage Stabilizer for Refrigerator As you can clearly see, all of them are from V-Guard. Be rest assured that we are not biased towards V-Guard. They actually make high-quality stabilizers and offers good customer service across India.
