Ecosine Economy FN3416

Ecosine 400-480 VAC 50Hz Economy Passive Harmonic Filters


Ecosine 400-480 VAC 50Hz Economy Passive Harmonic Filters

  • Economy line of passive harmonic filters for THDi <10%
  • Help to comply with EN 61000-3-12, IEEE-519 and other PQ standards
  • Support an efficient utilization of electrical system capacity
  • Ideal for motor drives with 6-pulse rectifier front-end
  • Suitable for diode and thyristor (SCR) rectifiers applications

Features and Benefits

FN3416 (50 Hz) models of the ECOsine product family represent the very compact economy line with a THID performance of >10% (with Ldc).

They are ideal for non-linear three-phase equipment with B6 rectifier front-end that do not require the industry leading <5% THID performance provided by Schaffner Ecosine Evo series.

The performance is still sufficient to comply with EN 61000-3-12 or with IEEE-519 for Isc/IL <50. Schaffner Ecosine filters help to unburden the electrical infrastructure from excess loading and heat caused by current harmonics, and therefore support a better utilization of electric system capacity.

Lower harmonics also reduce the risk of system resonances and potential downtime of sensitive electronic equipment.

FN3416/18 filters upgrade standard motor drives to low-harmonic drives quickly and easily.

Typical Applications

Three-phase power conversion equipment with front-end six-pulse rectifier (diode or SCR)
Motor drives, like those used e.g. in pump and fan applications
Battery chargers, incl. DC fast chargers for e-cars
