Features and benefits

FN 3418 LV (60 Hz) models of the ECOsine product family represent the very compact “economy line” with a THID performance of ≤7% (with Ldc).
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.
FN 3418 LV 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

Performance characteristics (for diode rectifiers)

THID – Total harmonic current distortion

ECOsine high power passive harmonic filter performance is optimized for rectifiers/motor drives with a dc-link choke. In such applications, a THID of roughly 7% can be expected. The use of a dc-link choke is highly recommended. In a system without Ldc a THID of 13% can be expected.

Displacement power factor

At full load, ECOsine filters yield unity power factor. At lower load levels, the capacitive current into the power capacitors of the trap circuit cause a leading displacement power factor. This is the case with all types of passive filters with large capacitors. However, compared to traditional filters the useful range of Schaffner ECOsine is much extended (cos phi >0.9 from 35 to 100% of rated load).

DC-link voltage

ECOsine harmonic filters have a very low impact on the dc-link voltage of the motor drive. The voltage boost/buck as a function of load can be seen in the performance graph beside. Tolerances are kept narrow in order to ensure that motor drives do not suffer from nuisance tripping because of under- or over-voltage situations.

Filter application

ECOsine filters are best installed directly at the input of 6-pulse rectifiers. It is possible to connect several non-linear loads (e.g. motor drives) in parallel. In this case the rating of the filter must match the sum of the power ratings of drives connected to it. The use of a (built-in) DC-link choke is recommended for best harmonics mitigation performance. If the expected input power exceeds the rating of the largest available filter, and a custom solution is not desired, then two or more filters can be wired in parallel. In this mode of operation, it is recommended to use filters with equal power ratings to ensure proper current sharing.
