Variable speed drives are increasingly present in industrial environments and pumping systems, generating harmonic currents in distribution networks that affect the correct functioning of the grid.
The FQP Freemaq harmonic filter is installed at the entrance of the drive and is designed for both the SD700 range of Power Electronics as well as other commercial inverters.
With a more compact and efficient design, Freemaq FQP provides a higher degree of harmonic filtering through more stable tuning that provides THDi values below 5%, in compliance with IEEE519.
Its construction is based on the installation of one or more filter modules in parallel that will be controlled and protected at all times by the drive. A range that would fit the most demanding applications.
