Ecosine 400-480 VAC 60 Hz 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
FN3418 (60 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.
