Schaffner is setting a new benchmark with its product offering of harmonics mitigation solutions. Ecosine evo harmonic filters utilise superior technology to reliably control excessive power line harmonics with an evolutionary modular product concept.
With the new ecosine filters FN 3441, FN 3451 and FN 3453 (pictured) Schaffner does now also offer dedicated filters which are designed for three-phase diode rectifiers with 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 designed for purpose and compact passive harmonic filters available on the market.
The filters offer excellent performance at rated power with minimal reactive power even at partial or no-load conditions. With the installation of the new ecosine filters the electrical infrastructure and its utilization are much more efficient and reliable. Added benefits of installation include increased service life cycle of electrical equipment and reduced energy costs.
The ecosine evo filter series modular design concept, which now includes filters for drives with and without a DC-link choke, offers flexibility unique in the marketplace. It allows Schaffner to provide customers with an optimal solution by offering base modules that are dedicated to the drive technology. These can easily be configured to meet specific application and customer needs as well as installation requirements by merely plugging in add-on modules. This modular concept allows the new Schaffner filters to provide tailored solutions for all applications, aligning product offerings with the international market requirements and customer expectations.
Ecosine evo filters FN 3440/41 FN 3450/51 and FN 3452/53 are rated for 50 Hz/400 VAC, 50 Hz/500 VAC and 60 Hz/480 VAC grids, respectively, with standard power ratings available from 1.1 to 250 kW (1.5 to 300 HP for 60 Hz filters). They are available as open frame IP 00 and protection category IP 20 (IP 21 as an option). All filters are CE-marked, UL listed and RoHS compliant.
