300kVA Split-Regulating Full-Automatic Compensated Voltage Stabilizer/Regulator

Feature:
The Split-Phase Regulating Full-Automatic Compensated Voltage Stabilizer/Regulator is composed of three sets of single-phase voltage stabilizer by 'star-shaped' connection. With the function of three phases independently voltage-stabilizing, it applies to the unbalanced input voltage of three phases 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 voltage parts of this series voltage stabilizer is adopted the pillar, Therefore, it has more power and more reliability.

Application:
It is widely used in the place with large electricity demands such as factories, post & communication, schools, hotel etc., acted as whole voltage-stabilization single voltage-stabilizing.
