MCGD Compensation Controller
The MCGD reactive power compensation controller is suitable for both high- and low-voltage distribution systems and operates based on reactive power. It employs a high-performance microcontroller, features a digital design, and includes an RS485 communication interface; the power quality data it acquires can be transmitted to external devices via this interface. The product offers protection functions for common‑phase compensation, overvoltage, undervoltage, harmonics, and overheating. With switching strategies that include cyclic, linear, and fast modes, it provides automatic, precise compensation control, thereby improving the system’s power factor and enhancing power quality.
