Product Description
The GPD-V series Dynamic Voltage Restorer (DVR) is an efficient power quality device designed for power systems, addressing voltage fluctuations and short-term voltage sags to ensure stable operation of critical and sensitive loads. It provides precise compensation during grid voltage anomalies, preventing voltage dips and outages.
The GPD-V system employs high-performance inverters and energy storage to respond to voltage fluctuations in milliseconds, outputting stable voltage continuously, boosting grid efficiency and equipment reliability. Its intelligent control supports real-time monitoring and auto-adjustment, with modular design for easy capacity expansion.
