Passive Harmonic Filter
StaffHarmonic Drive Schaffner
Schaffner's Ecosine evo filters are rated for 50 Hz/400 VAC, 50 Hz/500 VAC and 60 Hz/480 VAC grids with power ratings from 1.1 to 250 kW.
The new Schaffner ecosine filters FN 3440, FN 3450 and FN 3452 are designed for three-phase diode and thyristor rectifier, are achieving a THID ≤ 5% even without DC-link choke included in the drive. They guarantee compliance with the toughest requirement of IEEE-519 and other stringent international power quality standards. The filters offer excellent performance at rated power with minimal reactive power, even at partial or no-load conditions. Ecosine evo filters FN 3440, FN 3450 and FN 3452 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 and NEMA 1/NEMA 3R (only in the US) as a future option). All filters are CE-marked, UL listed (pending) and RoHS compliant. The ecosine evo filters are easy to install and maintain and are be fully supported in Schaffner’s well known power quality simulator SchaffnerPQS3.
