5 Best Voltage Stabilizers For AC In India 2021

About 15 years back, my father bought an AC for his parents living in a remote village in Kerala. The earnest salesman tried to sell him on the well-known V-Guard stabilizer for AC. But for some reason my father wasn’t sold on the idea. He saw it as a marketing gimmick because by that time, voltage fluctuation in most areas in Kerala were almost stable. Little did he know that is not entirely true!
One fine night, when the AC was running, the power surged and damaged the AC’s electronic components burning a heavy hole in my dad’s pocket.

Well, he learnt his lesson well and now every expensive appliance in my dad’s home has a voltage stabilizer.

Actually, a fact that we often forget is that voltage stabilizers are not just for regulating the ill effects of voltage fluctuations on appliances. We often forget that voltage stabilizers provide much-needed protection against power surges.

Power surges often have their source inside the house. Internal power surges can in fact happen when an electric device is suddenly turned off and stops drawing electricity. This results in a sudden spike in voltage throughout the home as the current it was drawing suddenly has nowhere to go. So, anytime you switch off your geyser, induction stove or any such appliance, your sensitive appliances like TV, Computers, AC, Gaming Console etc. runs a risk of being affected by a power surge.

Lightning, power surges originating from the electricity board, overloaded circuits, damaged or exposed wiring, power outages are some of the other causes of power surges.

Now that you know how important a role a voltage stabilizer plays in ensuring the life of your AC, let us take a look at the important factors to consider while buying one.

Which are the Best Voltage Stabilizers For AC in India?

If you are short on time, take a look at our recommendations below to make a quick right decision.

Our Recommendation
For a 1.5 ton AC, Microtek EM4150+ 150V-280V Digital Display Voltage Stabilizer is a good choice. Catering to a fairly wide input voltage range, with a smart delay feature, 3-year warranty and excellent brand reputation, this is one of the highly recommended options. Now, for a 2 ton AC, you would be better off with the V Guard VG 500 Voltage Stabilizer that comes with smart features, an input voltage range of 170 to 270 Volts and an economical price tag.

How To Choose An Appropriate Voltage Stabilizer For Your AC?

Not all stabilizer can be used effectively for all electronic devices. Each gadget has its own voltage limits and thus an appropriate stabilizer of the right size is required for an electronic device like the air conditioner. Moreover, various fine prints come into play to nail the right sized stabilizer.

Air conditioners are available in different capacities and with different energy ratings. Thus, each would need a specific size of the stabilizer. The size is determined by considering the following factors:

  1. Power consumption range of the air conditioner(s) that will be attached to the stabilizer. If you are connecting multiple air conditioners to the stabilizer; their power expressed in watts is cumulated. Then the resultant Watts value is increased by about twenty per cent to arrive at the load value that can be connected to the stabilizer. This value of the stabilizer is expressed as Volt-Ampere (VA) or Kilo Volt Ampere (KVA).
  2. The nature and capacity of the device and its energy ratings are the next considerations that impact the size of the stabilizer.
  3. Next, you must look into the range of the voltage fluctuation of your locality. This would give you the working range of your voltage stabilizer i.e. the range of fluctuation which can be handled effortlessly by the stabilizer in an effective manner.

Important Features to Consider when Selecting a Stabilizer for Air Conditioner

Different air conditioners consume different units of electricity and work on different voltages. We already know that these figures should be the main criteria while selecting the voltage stabilizer size. If they do not match, your air conditioner is likely to get damaged.

Apart from these, you must look into the following features while selecting the most appropriate stabilizer for your AC.

  1. Specialized stabilizer- Often people think of stabilizer in general terms. However, technological advancement has led to the availability of specialized stabilizers for various appliances. Thus, you must look into stabilizer devised specifically for air conditioners.
  2. The voltage range of your locality- Every locality has its own minimum and maximum limit of voltage fluctuation. The voltage range of your stabilizer must be equal to or greater than this locality range. If it is less; it would cut off the power supply and your AC would no longer function.
  3. Surge Protection- As mentioned earlier, surge protection is an important aspect to consider. Often during lightning or short circuits, a sudden spike in voltage is witnessed. This leaves the stabilizer with no time to adjust the voltage and both the stabilizer and air conditioner are likely to get damaged. To combat it, few stabilizers have surge protection or spike guard which can effectively manage a sudden surge in voltage by cutting off the stabilizer output completely during the spike.
  4. Mounting- As with any electrical device, stabilizers too can become risky if they get wet, damaged etc. when placed on the ground or on other unsafe areas. Thus, they must be mounted high in a safe position and especially away from children. With plenty of voltage mounting options available, you can select the one best suited for you.
  5. Voltmeter Indicator- With this feature, you are able to track the voltage that has been regulated by the stabilizer. There is normally a light indicator for it. The latest models boast LED lights.
  6. Time Delay Systems- Most stabilizers for air conditioners have this feature installed in them. This system gives the compressor enough time to generate the required voltage and give out a uniform current flow especially during short power cuts.
  7. Digitized- Most of the newer models of voltage stabilizers are crafted with digital technology. This empowers them to easily adapt themselves to different voltage fluctuations and offer a layer of protection to many different devices. Thus, you would be able to use your digitized stabilizer not only with an air conditioner but with other devices as well like your TV, refrigerator etc.
  8. Thermal Overload Protection- This feature enables the stabilizer to protect the compressor during high-temperature burnouts.
  9. Design- Finally, you can choose stabilizers in various colours and styles so that they complement your home décor effortlessly.
