The AVR-100KVA three phase voltage stabilizer is an intelligent compensation-type AC voltage regulator designed for industrial and commercial equipment operating under unstable mains voltage.
It accepts 380V three-phase four-wire input with a ±15% voltage range and provides stable 380V output. The regulation accuracy is adjustable from ±1% to ±5%, making it suitable for CNC machines, industrial production lines, medical equipment, laboratory equipment and other voltage-sensitive loads.

The AVR uses a closed-loop feedback system to continuously monitor the input and output voltage.
When the mains voltage drops, the compensation transformer provides additional voltage to raise the output. When the input voltage rises, the system provides reverse compensation to reduce the output voltage.
This automatic compensation helps maintain stable voltage without intentionally distorting the output waveform.
The 100KVA three-phase voltage stabilizer is suitable for:
Maintains stable 380V output under fluctuating mains conditions.
Voltage regulation accuracy can be configured from ±1% to ±5% according to application requirements.
The compensation design processes voltage deviation rather than the entire rated power, with specified efficiency of ≥95% at full load.
F-class insulation and high-quality silicon-steel components support a specified 20-year design life.
Multiple protection and alarm functions help protect both the stabilizer and connected equipment.
