With the continuous development of the market, we have more and more customers in the Middle East market using our APF(Active Power Filter) equipment.

Active Power Filter is a perfect comprehensive solution to power quality problems with power grid such as harmonic wave, reactive power, and three-phase load unbalance. ZD-APF active power filter is connected in parallel, to detect the harmonic wave in power grid in real time, generate the reverse-phase compensation current through the converter, and dynamically filter the harmonic wave in power grid.
