Digital Active Harmonics Filters perform targeted PFC.

In addition to providing real-time mitigation of harmonic currents up to 50th order, ECOsine Active Filters immediately compensate for voltage dips and reactive power surges. Units continuously measure and analyze disturbances in power network and provide exactly opposite compensation current, responding in less than Â-½ ms. Filters are available in 3-phase/3-wire as well as 3-phase/4-wire...
