Three-Phase Servo Voltage Regulators

ELSIPOWER three-phase servo voltage regulators correct mains voltage fluctuations in three-phase systems so that connected equipment runs on stable voltage — for industrial plants, production lines, CNC machines, commercial businesses and three-phase buildings.

A microprocessor-controlled servo motor and variac monitor the input and correct the output automatically. Each phase is controlled independently, so different deviations on each phase are corrected separately.

On models with a protection unit, out-of-limit voltage, overload or phase loss trigger the relevant protection and the output is disconnected to protect the load; operation resumes in a controlled way when the mains returns to normal.
