I recently bought this PPS (Power Protection System) with built in TDR (Time Delay Relay) from Su-Kam. It comes in two ranges - 6 Amps and 16 Amps. When attached with your applicances, it takes care of high / low voltage cuts and saves them. It is so amazing that last week when there was exceptionally high voltage in my locality, I and my neighbours ended up with burnt appliances, but only my AC and Fridge was saved becaused I was using PPS with them.

It is so small and good looking. It is actually a substitite to the bulky old age stablizer. Another thing that my friend told me was that stablizers have their own electricity consumption. Even when you switch off your AC etc., you never bother to switch off the stablizer and hence the electricity bills are high. Also, when compared to the cost of stablizer, I spent peanuts on it. Keep up the innovations Su-Kam.
