The Qoltec Avr Multiprotection three-phase voltage stabilizer regulates voltage using a servo motor that moves the regulator arm and automatically corrects input voltage deviations. It stabilizes the output voltage at 380 V AC with an accuracy of ±3%. The monitoring system continuously tracks the power supply parameters and smoothly adjusts the voltage without manual intervention.
The three-transformer system includes three Variac autotransformers, with an independent control unit for each phase, L1, L2 and L3. The MultiProtection system protects against phase and neutral reversal, phase loss, incorrect phase sequence, neutral loss and overvoltage. The LCD displays the voltage and current readings for each phase in real time, along with indicators for low or high voltage, overload, overheating, phase loss and active startup delay.
