Passive harmonic filters target 380 to 415 VAC 60Hz networks
Schaffner has extended its ecosine evo line passive harmonic filter series from 380 to 415 VAC, 60Hz to reliably mitigate excessive harmonics with an evolutionary modular product concept.

The ecosine evo FN 3442 and FN 3443 are dedicated passive harmonic filters for three-phase diode and thyristor rectifiers. They can achieve a THID ≤ 5% with and without a DC-link choke included in the drive. They guarantee compliance with the toughest requirements of IEEE-519 and other stringent international power quality standards while being the most dedicated and compact passive harmonic filters available in the market. The filters offer excellent performance at rated power with minimal reactive power, even at partial or no-load conditions. When incorporating ecosine evo filters the electrical infrastructure is unburdened and its utilization is much more efficient and reliable. In addition, the service life cycle of electrical equipment is extended, and energy costs can be reduced. Adding this extension to the existing six product families of ecosine evo filters FN 3440/41, FN 3450/51 and FN 3452/53, ecosine evo can now cover networks of 380 VAC to 500 VAC, 50 Hz/60 Hz. Ecosine evo filters FN 3442/43 are available with standard power ratings from 0.9 to 177kW. They are available as open frame IP 00 (-E0XXXXX, -E0FAXRX, -E0FAJRX) and IP 20 (-E2FAJRX) versions.
