JKL8CM/8BM Series Intelligent (digital display) reactive power compensation controller, suitable for low voltage distribution system capacitor compensation device special controller. And adapt to various parameters distribution coefficient, stable and reliable Operation, thoroughly compensation, simple operation, make the power factor to achieve the user preset, improve the transformer utilization efficiency, reduce line loss, improve the quality of the supply voltage.

¤ Switching capacitor by calculating the reactive power, it has high precision compensation.
¤ Initial phase preset (software control the identical terminal or current signalpolarity).
¤ There are the power factor and reactive power two kinds control mode.
¤ Through three key operation, achieving automatic operation, manual operation, parameter setting.
¤ Switching ways by the user to select
¤ Data permanent preservation no loses after power cut off.
