KEMOT PROavr-50k estabilizador de tensión trifásico automático 50 kVA

Automatic three-phase servo motor voltage stabilizer delivering 50 kVA of precise power conditioning for industrial and commercial installations. Maintains a stable 3 x 400 V output even when input fluctuates between 280 V and 430 V, protecting sensitive machinery from voltage sags, surges, and phase imbalance.

Advantages

High efficiency above 95% reduces energy waste and operating costs. The LCD display provides real-time status of input/output voltage, load level, and fault conditions. Integrated protection against overload, overvoltage, undervoltage, short circuit, and overheating ensures uninterrupted operation. Fan cooling and Class B insulation allow reliable performance in demanding environments.
