ecosine active sync
modular, compact, effective and reliable

Almost all electrical and electronic loads, whether in industrial plants, buildings or data centers, work non-linearly today. This has strong repercussions on the grid and dramatically degrades its power quality. The new ecosine active sync as a powerful and highly dynamic active harmonic filter can reliably reduce such perturbations and thus ensure clean operation.

The modular design of ecosine active sync always allows a suitable filter size to be supplied and, in addition, the 60 A modules can be easily fixed to the wall or integrated into system control cabinets. Simply slide in and wire up – a filter from up to 300 A per cabinet is ready.
