ECOsine active harmonics filters (AHFs) continuously measure and analyze disturbances in the power network and provide an exactly opposite compensation current, according to the company. In addition to the global or selective mitigation of harmonic currents up to the 50th order, the filters are able to perform targeted power factor correction. Compatible with the international harmonics standard IEEE 519 as well as local utility codes, the products are available in 3-phase/3-wire and 3-phase/4-wire configurations for 480V and 400V grids, respectively, and with rated compensation currents from 30A to 300A. All 3-wire versions are UL-listed.
