Product Advantages
Real-time Voltage Monitoring
The static voltage regulator constantly keeps an eye on the three-phase input power and makes instant electronic adjustments to keep the output stable within a narrow, preset range.
Fast Digital Control
Equipped with high-speed ADC sampling and advanced digital control, the system can detect and correct voltage fluctuations in just milliseconds, ensuring reliable performance.
No Mechanical Switching
Using SCR/IGBT power modules or a PWM control stage, the regulator adjusts the voltage electronically — no mechanical taps, no wear and tear, and longer service life.
Clean, Stable Output
A built-in compensation transformer and filter ensure a pure sine wave output, keeping the waveform clean and free from additional distortion.
Smart Protection & Easy Control
Features include a touchscreen HMI, bilingual interface, automatic bypass, and remote monitoring, making the system simple to operate and highly secure.
Contactless, Precise Regulation
The non-contact design ensures spark-free, smooth, and precise voltage control, making it perfect for high-precision industrial equipment and sensitive electronics.
