Schaffner further broadens its product offering of solutions for the improvement of power quality. The popular active harmonic filters ECOsine Active are new also available for 3-phase 200V power grids, often used in some regions (e.g. parts of Asia) for commercial building applications. While the product family FN3420 with 50A or 100A of compensation current is designed for three-wire systems, FN3430 in four-wire technology can be used for networks with separate neutral conductor (30A and 60A). The highly compact design (IP20) allows the space-saving filter integration directly in the electrical cabinet. 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.
