9 Best stabilizers in India for AC (May 2021)

While buying a stabilizer, that supports and protects your air conditioner against all power fluctuations, we need to look out for some specific features.

What are those important features you should look out for in a Voltage Stabiliser?

 Let’s see:

●Mount ability: stabilizers need to be mounted away from the reach of children, a place where water and direct sunlight don’t reach. Hence wall mounted air conditioners are preferred.


●Digital displays: This feature comes in handy as you can know at a glance whether the voltage is sufficient enough to power your AC. This feature is usually included in all stabilizer brands.

●Time Delay Systems: In case of electricity cut-offs, a Time Delay system comes handy. It gives enough time to the compressor of your air conditioner to balance out the current flow, thus keeping your AC protected.

 ●Overload Current Protection: An Overload Current Protection feature turns off the stabilizer output if a short circuit occurs. This saves from any kind of burnout.

How You Can Choose the Best Voltage Stabilizer for Your AC?

Well, let us break it down to you in simple steps:

First, find and read the specifications sticker on your gadget. You may find a user guide too with all the specifications written. Get a glance at the voltage, current, and power rating of the appliance. In the case of India, the standard service voltage is 230VAC, 50Hz.

Then, you should know the power capacity in Watts of all the appliances you wish to connect your stabilizer to. Why?

Because it will give you an idea of the power load your stabilizer will be facing in Watts. As most stabilizers in India are in the size of VA or kVA, you can increase the value of Watt by 20% to know the exact power load.

Let us understand it by example.

If 1000 Watts of appliances are connected with the stabilizer, then you will have to purchase a 1200 VA or 1.2 kVA stabilizer. It can range on a wider scale too, depending on the power fluctuations of your locality and the grid-connected to your home.
