KEMOT PROavr-80k Automatic Three-Phase Voltage Stabilizer 80 kVA

Industrial-grade automatic three-phase voltage stabilizer delivering 80 kVA of clean, stable power for demanding commercial and industrial loads. Its servo motor control ensures smooth, step-less voltage correction, maintaining output within ±3% of 380 V AC even when input fluctuates between 280 and 430 V AC.

Advantages

Servo motor technology provides precise, harmonic-free voltage regulation without introducing distortion. The unit operates at over 95% efficiency, minimizing energy waste and heat generation. A manual bypass switch allows maintenance without interrupting power to connected equipment. Comprehensive protection—overload, overvoltage, undervoltage, short circuit, and overheating—safeguards both the stabilizer and downstream devices. The clear LCD display offers real-time status monitoring, while forced fan cooling maintains safe operating temperatures up to 40°C.
