Active filter technology is the result of extensive research, and it has been proven to provide lowered disturbances, lower current consumption and increased production stability, just to name a few.
The active filter power range fluctuates between 30 A up to 2,800 A with 400 VAC to 690 VAC on the active side. They can either be wall-mounted up to 120 A or in complete cabinet IP21/40 construction. Load current transducers are mounted separately.
Possible active filter connections to the grid:
