Voltage Stabilizer for Professional Equipment

Three-Phase Servo Motor Control System

The stabilizer uses SERVO control technology, where a servo motor controls the position of the regulator’s moving arm. This solution allows the unit to automatically respond to changes in the power supply parameters and smoothly regulate the incoming voltage without manual intervention, ensuring a stabilized 380 V output voltage.

Accurate Output Voltage Stabilization ±3%

The stabilizer maintains the nominal output voltage at 380 V AC with an accuracy of ±3%. This means that during normal operation, the output voltage is stabilized within approximately 368.6–391.4 V AC. The measurement system continuously monitors the supply parameters, while the servo motor control system automatically corrects any deviations in the incoming voltage, minimizing the impact of power grid fluctuations on the connected equipment.

Monitoring of Each Stage for Greater System Safety

3-transformer system - Independent voltage control and regulation in each phase

Models with a rated power of 10 kVA or higher are equipped with a 3-transformer system, consisting of three Variac autotransformers. Each phase has its own control unit, allowing independent voltage regulation of phases L1, L2, and L3.

Multi-Level Protection System for Three-Phase Installations

The integrated Multi-Protection system helps reduce the risk of damage to machines, industrial equipment, and other three-phase loads.

• Phase and neutral wire reversal
• Loss of one phase
• Incorrect phase sequence
• Loss of neutral wire
• Excessive overvoltage

Stable Voltage for Heat Pumps, Compressors, and Electronic Control Systems

The voltage stabilizer is available in rated powers from 10 to 40 kVA and can be used for:
