Qoltec Three-Phase Voltage Stabilizer AVR MULTIPROTECTION 10kVA ±3% Servomotor 3F LCD Expert Line

Three-phase automatic voltage stabilizer with servomotor technology delivers a robust 10kVA power capacity and precise ±3% output regulation, safeguarding industrial equipment from harmful mains fluctuations. The MULTIPROTECTION system continuously monitors input voltage and instantly corrects deviations, ensuring a stable 380V AC supply for motors, CNC machines, and sensitive electronics.

Advantages

Servomotor-driven stabilization reacts in under one second, while the wide 280–430V AC input range handles severe grid instability. The high-efficiency design (>95%) minimizes energy waste, and active cooling keeps components within safe thermal limits. A clear LCD panel provides real-time status, and selectable delay (6s or 180s) prevents rapid restarts after power interruptions.
