Bumping the old thread. I am facing severe power issue in chennai. The voltage drops a lot 120V sometimes. Just a week before I bought 4KVA V guard stabilizer for 4K. This double booster stabilizer can boost the voltage as low as 130V. Initially I thought our line wont go down as low as 130V hence bought the double boost. Many ppl are using A/C’s in our area and when the neighbours compressor starts off I can see huge drop of 20V in our line. 150V will become 129V. The stabilizer works till 127V and boost till 193V anything below 130V is a sure sign of cutoff for 3 mins. I feel the double booster in my area is useless. I asked my neighbour what stabilizer he uses. He told me a local one with “triple pick-up” costed him 7k. Shall I go with servo based stabilizer or triple boost stabilizer.

Vijay
