Product overview

ULHB307 dynamic reactive power compensation controller, is a professional committed to the distribution network harmonic management dedicated controller. The ABB industrial border quasi, choose the first DSP resistance to harmonic technology and resistance to harmonic touch block circuit, in very bad power grid environment can work normally. High and low voltage is the power of harmonic management, filtering, the reactive power compensation of the best choice.
