Frequently Asked Questions (FAQ)

1. Does the voltage stabilizer need to be on every time?

It depends upon your usage scenario. If the appliance you are using the voltage stabilizer for requires constant power delivery, then yes, you must keep the voltage stabilizer on every time. If your appliance does not require constant power delivery then, you may turn off the voltage stabilizer for a while until switching it on is required.


2. How much electricity does a voltage stabilizer consume?

The amount of electricity consumption of any voltage stabilizer depends on its kVA rating. Most of the voltage stabilizers are highly power-efficient, around 95-98%. They consume about 2-5% of this efficiency percentage, which is very low.


3. Is one voltage stabilizer sufficient for an appliance?

Yes. In most cases, a single voltage stabilizer can easily support 2-3 small to medium-sized appliances like TV, PC, etc. If it is an air conditioner or a refrigerator, it is highly recommended not to add any other appliance on the same voltage stabilizer.


4. How long does a voltage stabilizer last?

Generally, an average voltage stabilizer works fine for 3-4 years but, this can vary as per your usage. Apart from that, environmental as well as electricity plays an important role in the lifetime of the product.
