Feautre The three-phase Adjustable Compensation Voltage Stabilizer is composed of three sets of single-phase voltage stabilizer by "star-shaped" connection. With the function of thee phases independently voltage-stabilizing, it applies to the unbalanced input voltage of three phases or unbalanced three phase loads. reover, 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.
