Schaffner broadens its product offering of solutions for the improvement of power quality. The active harmonic filters ECOsine Active are now also available for 3-phase TN and IT 500 - 690 V power grids. The filters provide the system with an opposing corrective current immediately, compensating harmonics, phase shift and load-unbalance at the same time. They dynamically adapt to changing grid and load situations, providing an optimum compensation performance at all times. The new active filters for three phase networks on the level of 690 V/50 Hz or 600 V/60 Hz are often used in heavy industry, chemical industry, mining or oil exploration. The new active filters with the designation FN 3420-200-690-3 can be programmed to the specific needs of the application and provide up to 200 A of corrective current. If more is needed, up to 10 units can be paralleled at the same set of current transformers. State-of-the-art power electronics with 3-level technology are at the core of the new filters, helping to significantly reduce power loss. The 690 V active harmonic filters come in sturdy IP54 rated cabinets. A UL-approved version (FN 3420-200-690-3-UL) is currently in preparation.
