Product Overview
Our company’s JL-APF series active power filters are available in both wall-mounted and rack-mounted configurations. The JL-APF unit can simultaneously address various common power quality issues in power distribution networks. Widely used in industries such as iron and steel metallurgy, petrochemicals, cement and building materials, machinery casting, photovoltaics, high-end manufacturing, new energy vehicles, semiconductors, lithium batteries, shipbuilding, airports and ports, municipal and commercial sectors, and textiles and papermaking, it resolves common problems including:
Excessive power factor, current imbalance, voltage flicker, current harmonics, and overvoltage issues. It improves power supply quality, ensures the safe and reliable operation of user equipment, and achieves energy savings and efficiency improvements.
