I buy this voltage stabilizer for my home AC. And I want share my experience about this stabilizer which is not so good. In summer the voltage at our home is going up and down. I am using thia stabilizer with my AC but after use of thia stabilizer my AC is not getting required voltage to run. And it is getting on and off because of lack of voltage. I call both the engineers of AC and stabilizer too. AC is working fine but the problem is with stabilizer the service centre replace the stabilizer but problem is not solved yet.
