Product Description
Product Name: SFR-APF harmonic suppression automatic compensation Active Harmonic Filter
An increasing number of loads are non-linear, introducing harmonics into the power grid and thus significantly impairing the power quality. SFR-APF is an active harmonic filter that effectively reduces the unwanted harmonics.
