Top 10 Best Stabilizer For AC 1.5 Ton In India 2020 Reviews

Power-cuts and voltage fluctuations are a common norm for a large part of the Indian population even today. While power-shortage has been addressed in most areas during recent times, however, voltage fluctuations still remain one of the main concerns. India is an ever-growing nation. With the development in the field of technology and electronics, the country has found itself with multiple options when it comes to choosing its appliances.

The field of electronics has been booming ever since. The electronic market today is brimming with devices and appliances that are designed to serve your everyday purposes and much more. However, the overall economic growth of a country severely affects its demand and market.

We are a superpower today but still struggle with basic necessities like water and electricity on a daily basis. While urban India has leaped-ahead, there is a population of the rural and developing regions that suffer the most when it comes to availing the basic necessities. 

While an average Indian home is equipped with almost all basic electronic appliances, however, the fluctuations in electricity supply or complete blackouts in certain cases deeply hampers the everyday livelihood. In many cases, children are forced to streetlamps to complete their homework or restoring to other means which in return affects their eyesight. But you have the field of technology once again to thank to, for inventing devices that are designed to deal with the issues of power-cuts and voltage fluctuations all together. One such gift of technology is the Stabiliser.

For an average Indian home, a stabilizer has a permanent place to stay. In fact, there are cases where a stabilizer is purchased before you decide upon buying the rest of your other electronic appliances. So, what exactly is a Stabilizer all about? Let us take a look.

The electric power lines in India are often hindered with voltage fluctuations.  Most often, these fluctuations are so rapid and harmful that they badly damage your electrical appliances. Many times, electronics such as Fridge, air-condition, television, and ovens are left damaged permanently with no options for repair. The answer to your woes lies in a stabilizer.

As the name suggests, the Stabilizer basically stabilizes your voltage fluctuations and protects your electronics from damage. This is done by stabilizing the utility voltage before it is allowed to enter the electronic appliance. The main aim of the stabilizer is to identify the voltage fluctuations from the main utility source and regulation it internally to offer a steady supply of voltage.

So, in case the main utility voltage is low, the stabilizer senses it and boosts it to the desired level of voltage and then allows it to feed into the appliance it is connected to. Likewise, if the voltage is high, the stabilizer modulates it to the required level and allows it to enter the appliance.

The desired voltage is achieved through the high-quality electromagnetic rays that change the taps in an inbuilt autotransformer in an electronic circuit. The main purpose of the working stabilizer is to function as a safeguard between the main utility source and the electronic appliance.

So, how do you decide which one is Best Stabilizer For AC? Let us take a look at a few pointers:


Things To Consider Before Buying Best Stabilizer For AC In India

  • Stabilizer Ratings

You need to check the Current, Power, and Voltage of the device. You will usually find these details in the user manual or the power socket of the device. So, if the standard service voltage of your mains supply is 230 VAC, so to get the maximum power:

-230 X Max rated current of all the equipment that needs to be connected to the stabilizer

– Add another 20-25% more for safety margin into the final value to finalize the stabilizer rating.

  • Working Range

Each stabilizer has a Voltage range within which it operates. This is the range which the device stabilizes the input utility voltage, thus, providing the required voltage output. So, to understand the kind of Stabiliser that you might require, it is important to understand the voltage fluctuation range that occurs in your locality.

  • Mounting

It is important to understand where you are going to place your stabilizer. Since a stabilizer is an electronic device, it is important to understand that there are few basic guidelines to follow. Make sure your stabilizer is wall-mounted or placed safely out of reach from children. This ensures that the device does not come in contact with water or any other such agents.

  • Indicators

A good quality indicator displays the voltage that has been regulated to supply the required power to the appliance. The latest models have LED displays as well.

  • Time Delay System

It is important for the in-built compressor to avail enough time that is required for a balanced power flow. The time Delay system functions to allow that ‘time-lapse’ in case of rapid power cuts.

  • Digitized

A digitized stabilizer makes it easier to get compatible with as many and various different appliances. Most of the latest models in stabilizers are digitized, making them more accurate and reliable to use.

  • Overload Protection

This is perhaps one of the most important features of a good stabilizer. The Overload protection ensures complete turn-off of the Stabiliser output during short circuits or burn-outs. This usually occurs in the case of overload.

Are the modern appliance available with in-built stabilizers?
Most modern-day appliances are engineered with larger voltage range. Earlier models of refrigerators usually worked within the range of 200-240 V, however, now the latest models have a wider working range. While the appliances might have inbuilt high and low voltage cut-off but do not have a stabilizer built within. However, while a stabilizer might be recommended, but it is necessary to check the voltage range of your area and only then decide on one.
Do different appliances require different stabilisers?
Generally, stabilizers are manufactured by keeping the energy limit into consideration. As every household appliance has its own energy limit, it might be possible that a certain stabilizer might not be compatible with a particular appliance.

However, the recently designed stabilizer usually offer a wider voltage range, more than one appliance can be attached to a single stabilizer. When selecting a stabilizer, it is important to bear in mind your requirements and the voltage range of your area as well.

What is the difference between a Voltage stabilizer and a Voltage regulator?
Both the Voltage stabilizer and the voltage regulator have the same functions. However, it must be understood that a voltage stabilizer is a device which is used to ensure the constant voltage to the output without altering the incoming voltage.
What are the main differences between a Stabilizer and a Servo stabilizer?
A stabilizer is basically an electronic circuit which functions to provide corrections to the voltage. The Servo stabilizer, on the other hand, is basically an electromechanical device, so its voltage correction speed is comparatively slower to that of a stabilizer.
Do stabilizers help conserve electricity?
In theory, a stabilizer functions to maintain the power consumption stable. However, the working of a stabilizer wastes about 5% of energy on an average. So, practically speaking you actually are not saving any amount of electricity by using a stabilizer.

Final Notes

Stabilizers are efficient devices and essential for areas where power cut-off is the main reason.  Since our everyday lives are impossible to imagine without household appliances, so having a stabilizer is only a practical decision. However, there are a few factors that you need to keep in mind when selecting the right kind of stabilizer for your home.

Certain features such as thermal overload protection is a must-have. Due to rapid voltage fluctuations, the appliances and the stabilizer both face the dangers due to overheating.  There are also other features like the ‘time-lapse’ technology that is an important factor for a stabilizer. The time-lapse technology is designed to protect your compressor when facing frequent voltage hikes and low.

As modern times and lifestyles are all about aesthetics, it is also important for your device to compliment your home. The latest models in stabilizers are quite compact and stylish giving it a nice appeal. The LED display is another useful feature much preferred by the consumers today.

It allows you to understand the reading instantly. While opting for a stabilizer it is important to understand that it is an electronic design and needs protection. It is best preferred to go for a wall-mount design as that way the stabilizer will be out of the way and safely tucked away from kids and other factors. Happy stabilising 🙂
