Key Features
Product Overview
JKW-HV-M Series High-Voltage Automatic Reactive Power Compensation Controller (hereinafter referred to as the controller) adopts the combined control of fundamental power factor and fundamental reactive power to switch capacitor banks. It features stable switching without oscillation and low sensitivity to harmonics. It can accurately display power data and control switching operations. Equipped with a character LCD large screen, it provides a user-friendly human-machine interface with convenient operation and attractive appearance. With PT configuration, it is applicable to the automatic control of reactive power compensation in high-voltage systems.
