Ecosine Flex, 400-480 VAC 60 Hz 10% THDi Passive Harmonic Filters
- Reduce THDi to 10% (15% if no DC-Link present in the drive)
- Filters for diode rectifier with and without DC-link choke and thyristor rectifier
- Help to comply with EN 61000-3-12, IEEE 519 and other PQ standards
- Increase the efficiency of energy utilization
- Most compact design
- Plug and play, ready to use
Features and Benefits
FN3458 (60 Hz) models of the Ecosine Flex 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 filters.
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.
FN3458 filters upgrade standard motor drives to low-harmonic drives quickly and easily.
