Features and Benefits
FN3446 (50 Hz) models of the Ecosine product family represent the very compact economical series with a THDi performance of <10% for drives with 4% Ldc and <15% for drives without Ldc.
They are ideal for non-linear three-phase equipment with B6 rectifier front-end that do not require the industry leading <5% THDi performance provided by Schaffner Ecosine Evo series.
The performance targets the requirement of EN 61000-3-12 and 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.
FN3446 filters upgrade standard motor drives to low-harmonic drives quickly and easily.
