ECOsine^® Active – new harmonic filters for 690 V systems

The Schaffner Group further broadens its product offering of solutions for the improvement of power quality. The popular active harmonic filters ECOsine^® Active are now also available for 3-phase TN and IT 500 – 690 V power grids.

Nowadays, an increasing number of energy-efficient electrical consumers are used in industrial applications, including variable speed drives for motor control. These modern technologies contribute significantly to the reduction of electrical energy consumption; however, as an unwanted byproduct of their operation they can negatively affect the power quality.

ECOsine^® Active harmonic filters deliver a reliable remedy. They 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.

New in the Schaffner product offering are active filters for three phase networks on the level of 690 V/50 Hz or 600 V/60 Hz, 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.
