Servo Voltage Stabilizer (Three Phase)
Robust three-phase servo voltage stabilizer designed for industrial environments requiring stable power for heavy machinery and electrical systems. It supports wide input ranges (300–480 V variants) and delivers precise output voltage of 400 V or 415 V ±1%. The microcontroller-based control circuit, step-less voltage correction through a variable transformer, and fast correction speed ensure smooth and reliable operation. With capacities from 15 kVA up to 3000 kVA, it is suitable for factories, production units, large commercial buildings, and other high-load applications.
Dedicated engineering support available for custom configurations.
