Schaffner Introduces power quality solutions for industrial power systems

ECOsine Active continuously measures and analyses disturbances in the power network and provides an exactly opposite compensation current. In doing so, the filter actively adapts to changing network topologies and responds in less than half a millisecond.

The use of ECOsine Active provides the user with a solution to complying with the stringent international harmonics standards as well as with local utility codes. ECOsine Active also ensures that the electrical infrastructure is unburdened; preventing potential overheating of transformers, motors, cables etc. and the risk of premature failure of electrical equipment is reduced. The improved Power Quality minimises the risk of downtimes and process interruptions while saving energy and reducing operating costs.

In addition to the global or selective mitigation of harmonic currents up to the 50th order ECOsine Active is able to perform power factor correction in a targeted manner. In highly dynamic processes, for example welding robots, ECOsine Active provides the required reactive power within microseconds, significantly faster than traditional automatic capacitor banks.

ECOsine Active is easy to install and intuitive to operate. The compact package of ECOsine Active makes its use possible even when space is at a premium. The 50 and 100 Amp filters in the IP20 design are ideal for panel integration, so they can be installed right by the non-linear load. The IP54 rating of the 300A unit provides protection against dust and environmental influences, making it ideal for harsh industrial applications.

ECOsine Active is available in 3-phase/3-wire as well as 3-phase/4-wire configuration for 480V and 400V grids respectively and with rated compensation currents of 30 to 300A. All 3-wire filters are UL listed and therefore ready for the North American market. Building technology and HVAC installations, heavy industry, data and banking centres, UPSs, water/wastewater treatment facilities, or welding equipment can equally benefit from the many advantages of ECOsine Active.
