Schaffner's new filter series with the designation FN 3416LV (50 Hz) and FN 3418LV (60 Hz) extend the application range of the ECOsine® Economy Line down to 200 V to 240 VAC and offer a cost-effective solution for harmonics mitigation particularly suitable for applications requiring superior THDi performance and with limited available space.
Both new series are intended to be used for harmonic mitigation of three-phase installations with diode or thyristor bridge interfaces, enabling to achieve a target THDi of < 7% in presence of a DC-link inductor. Furthermore, both rectifier peaks current as well as RMS input current are reduced and the grid current is back to its sinusoidal shape. Lower electrical losses and improved power factor allow an enhanced and more efficient utilization of electrical system capacity.
The user-friendly filter concept allows for a quick installation and commissioning without the need of thorough system analysis and the involvement of specialists. The high performance is guaranteed not only at full load, but a power factor close to unity is possible even under demanding partial load operation. Even without DC-link choke installed and with no de-rating, a THDi of < 13% can be achieved.
