CONSNANT APF（Active Power Filter） isa specialized power electronics device designed for harmonic mitigation. With a rated capacity ranging from 50A to 200A, it supports rated voltages of 220/400/690VAC and covers both three-phase three-wire and four-wire configurations. It offers flexible installation options—including floor-standing, wall-mounted, and rack-mounted setups—and supports capacity expansion via the parallel connection of up to five units. The system is integrated into a cabinet using hot-swappable modules, facilitating ease of maintenance and management.
Capable of precisely filtering harmonics and optimizing power quality, the device is widely deployed across diverse sectors—including rail transit, petrochemicals, automotive manufacturing, heavy industry, municipal utilities, healthcare, smart buildings, and metallurgy—effectively addressing the power quality management requirements of various high- and low-voltage power distribution systems.
