Booster Stabilizer for Air Conditioners Buying Guide

Some important points to consider while purchasing an AC stabilizer are as follows:

1. Type and Brand of Your AC:

Not all stabilizers are suitable for all AC brands. So you need to look for the one that is suitable for your AC, to prevent any kind of issue.

2. Protection from Thermal Overload:

High-temperature burnouts are prevented when your stabilizer has this feature.

3. Digitized Stabilizer:

Such stabilizers ensure easy adaption to voltage fluctuations besides providing a protection layer to different electronic devices.

4. Time Delay:

This system provides enough time to the compressor for generating the necessary voltage and uniform flow of current, mainly during short power cuts.

5. Voltmeter Indicator:

You can track the voltage using this which comes with a LED light indicator.

6. Placement:

Stabilizers need to be placed in areas where there is no risk of getting wet or damaged. Make sure that it has the option to be mounted on the walls safely, away from kids, for safety.

7. Surge Protection:

This is an important factor mainly during lightning, short circuit, and voltage spike, which are most likely to damage the stabilizer as well as the device linked to it, as they won’t get time to adjust to the change. So the spike guard or surge protection results in the effective management of this voltage.

Voltage Stabilizer forms one of the most important ways of ensuring the protection of your AC. Since AC is an expensive appliance, you need to invest in a good stabilizer for the best experience.

Frequently Asked Questions (FAQs)

Q. How to determine the size of the stabilizer needed by your AC?

Ans – An AC’s power consumption will determine the size of the stabilizer. When more than one ACs are connected to a stabilizer then there is a 20% increase in the resultant Watt value. Kilo Volt Ampere or Volt Ampere (VA) is used for expressing this.
AC’s energy rating and range of voltage fluctuation also determine the stabilizer size.

Q. What is the standard stabilizer size needed for a 1.5 ton and 2 ton AC?

Ans – When you use a 1.5 Ton AC, a 4 KVA stabilizer has to be used and for a 2 Ton AC, 5 KVA stabilizer is needed.
