Harmonic filters address 3-phase 200V power grids

August 31, 2012 // By Julien Happich
The Schaffner Group further broadened its product offering with active harmonic filters, the ECOsine Active, now also available for 3-phase 200V power grids.

The units provide the power grid 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 active filters are available for three phase networks operating at 200 to 240V (50/60Hz), often used 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.
