How to Choose Stabilizer for AC?

All the home-appliances come with their specifications and features. In this section, we have some factors that will help you to find the best stabilizer for your home. Before buying a voltage stabiliser for your AC, keep these points in your mind:

Different electrical devices work on different voltages and use different units of electricity. So, there is a different type of voltage stabilisers for single-phase and three-phase voltage power supply.

The standard voltage in India is around 230 volts, alternate at 50 cycles (Hertz) per seconds.

Know the Load Connected to Your Stabilizer

The total power of any device can be calculated by multiplying 230 x max rated current.

(The current, voltage & power-rating of the invention is mentioned in the specification sticker or the user manual.)

Once you have an idea about the range of power-consumed by an AC, it will help you to select a suitable stabiliser for the air conditioner of your home.

Choose the Right Size of the Stabilizer

The size of the stabiliser is similar to that of an inverter or a UPS. All the stabiliser come in either Volt-Ampere (VA) or Kilo Volt Ampere (kVA).

1 kVA = 1000VA

You must calculate the correct amount of power of voltage stabiliser that you will need.

For instance, if the sum of watts connected to the stabiliser is 1000, then you need to take a 1200VA stabiliser.

The watt value must be raised by 20% to get an approximate value of VA size that is suitable for you.

The 20% value is only for households, but not for commercial purposes, as the power factor is terrible.

Mounting

There is always a risk of stabiliser getting damaged due to power surges or wet when placed on the ground or anywhere unsafe. Therefore these stabilisers will need to keep at a higher place than the ground level.

Keeping the stabiliser at a more important platform protects it from any damage, and it also saves children in the house from an electric shock or any injury.

Hence wall-mountable voltage stabiliser is recommended.

Time-Delay Systems

This feature of the stabiliser allows the compressor to enables a time-lapse to generate the required voltage. In the case of a power cut, this feature gives compressors sufficient time to balance the current flow and required voltage.

Indicators

It displays the voltage which has been regulated by the stabiliser.

Some of the great models include LED-indicator in the body.

Digitised

A lot of the advanced models are digitised to making the function of voltage stabiliser more accurate.

The digital technology of the voltage stabiliser helps it to adapt it to several appliances.

Overload-Protection

Some stabilisers have surge protection or spike guard that turns off the stabiliser output in case of short circuits or any burn-out. Most of the stabilisers come with copper windings, but some of the products use aluminium windings.


Frequently Asked Questions

1. How Much Electricity Do Voltage Stabilizers Consume?

Electricity consumption of the stabiliser depends on the efficiency of the stabiliser. It only consumes about 2-5% of the maximum load.

So if you have 1kVA stabiliser, it would consume about 50 Watts.

2. What Are the Reasons for Voltage Fluctuation?

Voltage fluctuation can cause due to bad wiring, overload, sudden switching on of high powered devices (like refrigerators, air conditioners), bad earthing, or short circuits.

3. Does a Stabilizer Give Constant Voltage Output?

Voltage stabilisers stabilise the voltage to the load. These are not meant to provide a constant output of voltage.

It runs the device in a safe voltage range.

4. Can Regular Stabilizer Be Used for the Air Conditioner?

No, regular stabiliser can’t be used for the air conditioner. For AC, you need extra safety. The intelligent time delay system (ITDS) technology ensures maximum protection to the AC.

5. Does Stabilizer Reduce the Electricity Bills?

The stabiliser will keep your power consumption stable and may reduce it. However, the stabiliser itself wastes up to 5% of the energy unless you run it at peak load.

It only protects the load from brownouts and surges.
