Detailed Product Description

This series large power Voltage Stabilizer is composed of three sets of single-phase voltage stabilizer by star-shaped connection. With the function of three phase or unbalanced three phase loads. Moreover, it has the functions such as voltage regulating stability, high voltage stabilizing precision, and auto-balance of three phases. The regulating voltage parts of this series voltage stabilizer is adopted the pillar. Therefore, it has more power and more reliability.
