Product name | Intelligent Reactive Power Compensation Controller | ||
Product model | FJK-02-12F | ||
Product introduction | FJK-02 intelligent reactive power compensation controller is suitable for automatic adjustment of capacitor compensation device in low-voltage distribution system (controller for short). It enables power factor to reach user's preset state, improves utilization efficiency of power transformer, reduces line loss and improves power supply quality, thus improving economic benefits and social benefits. | ||
Functional characteristics | 1. Fully digital design, AC sampling. The human-machine interface adopts large-screen LCD and Chinese liquid crystal display. 2.Adhering to the people-oriented design concept, modular assembly and streamline design. 3. Real-time display of power factor,voltage, current, active power, reactive power, total harmonic distortion rate of voltage, total harmonic distortion rate ofcurrent, frequency, temperature, capacitance output display, switching status alarm and other information of L1, L2 and L3 phases. 4. Set Chinese prompt for parameters and enter numbers. 5. Capacitor control scheme supports three-phase compensation, split-phasecompensation and comprehensive compensation scheme. Control scheme can be set through menu. 6. It has two working modes of manualcompensation/automatic compensation. 7. The sampling physical quantity is reactive power and has harmonic measurement andprotection functions. | ||
