Key Features
Product Overview
JKWHD‑M Series Automatic Reactive Power Compensation Controller adopts combined control of fundamental‑wave power factor and fundamental‑wave reactive power for capacitor bank switching. It delivers stable switching without oscillation and low sensitivity to harmonics. It can accurately display power data and control switching operations. Equipped with a large character LCD screen, it features user‑friendly human‑machine interface, easy operation and elegant appearance. It is suitable for automatic reactive power compensation control in 0.4 kV systems.
