BRVC -D/DC Low voltage reactive power auto-compensation controller

        It is the new-developed low-voltage reactive power controller which had absorbed the advanced technology of home and abroad. Showing real time grid power factor, voltage, current, total harmonic distortion and capacitance switching status and other information, with harmonic, overvoltage and under voltage protection and priority combined cycle and encoding switching, for this, it can balance working life of each capacitor, also compensate the reactive power best to improve power factor.
