Relay type automatic voltage regulator is mostly used for home appliances in many countries where there is unstable grid electricity supply. this series of automatic voltage regulator is featured with energy saving due to grand new high efficiency toroidal transformer is used. according to our comparison with tranditional cheap EI transformers based AVR, this AVS-2000 can save as much as 360KWH electricity per year, which is much more than the value of a 2000VA stabilizer. It can achieve such high level of energy saving because its idle current is 0.11A compared to 0.4A of most EI transformer based AVR.
