Powerhome three phase autotransformer solution designed for stable and efficient voltage conversion between electrical systems operating at different voltage levels. The three phase autotransformer is able to utilize the existing input voltage more efficiently while reducing energy loss and installation complexity. Compared with conventional isolation transformer systems that require larger structures and full power conversion, the Powerhome three phase autotransformer provides a more compact and cost-effective solution for industrial voltage conversion and power distribution applications.

Typical Powerhome three phase autotransformer models support input and output voltage combinations such as 220V, 380V, 400V, 415V, 440V, and 480V, with frequency options of 50Hz and 60Hz. Available power ratings range from 1kVA to 500kVA for industrial and commercial applications. The autotransformer design helps reduce copper material usage and improve conversion efficiency while maintaining stable voltage output for connected equipment.
