Step-down auto transformer with continuous power of 750 watts. Ultra slim auto transformer for standard use and especially engineered for refrigerators, pumps, and fractional motors. PowerXchanger, the leading designer and inventor of the world's most advanced solid-state compact Voltage and Frequency Converter, is pleased to introduce its first Ultra Slim Step-Down auto Transformer. The home appliance and related industries are aware that compressors and fractional electric motors, such as those in refrigerators and pumps, that were designed to operate on 60Hz power supply, will run extremely hot while operating on a 50Hz power grid. This will result in a significant reduction in the life span of the product. PowerXchanger's new Step-Down Autotransformer eliminates this excessive heat problem allowing the appliance or motor to operate at normal temperature.
