Expanded product line of passive harmonic filters

Schaffner has extended its ecosine evo line passive harmonic filter series to 380VAC to 415VAC, 60Hz. The product range blends excellent technology to reliably mitigate excessive harmonics with a modular product offering an evolutionary concept and expands the availability of the company's filter solutions for customers and applications. The new ecosine evo FN 3442 and FN 3443 are dedicated passive harmonic filters for three-phase diode and thyristor rectifiers. They can produce a THID =5% with and without a DC-link choke incorporated in the drive. They ensure compliance with the toughest demands of IEEE-519 and other stringent international power quality standards while being one of the most dedicated and compact passive harmonic filters accessible in the market. The filters provide outstanding performance at rated power with minimal reactive power, even at partial or no-load conditions. When including ecosine evo filters, the electrical infrastructure is unburdened, and its utilisation is far more efficient and reliable. Also, the service life cycle of electrical equipment is increased, and energy costs can be decreased. Adding this extension to the current six product families of filters FN 3440/41, FN 3450/51 and FN 3452/53, ecosine evo can now cover networks of 380VAC to 500VAC, 50Hz/60Hz. The evo filters FN 3442/43 are offered with standard power ratings from 1HP to 240HP (0.9kW to 177kW). They are offered as open frame IP00 (-E0XXXXX, -E0FAXRX, -E0FAJRX) and IP20 (-E2FAJRX) versions. All filters are CE-marked, UL listed and RoHS compliant. The filters are simple to install and maintain.
