Filter combinations, single-stage
Description
The CNW 307 combined filter relieves the supply network by compensating for harmonic reactive power. The harmonic harmonics are reduced to THD < 60%. This improves efficiency and relieves the line. The mains choke also limits the mains interference that occurs, such as current peaks and voltage drops in the mains. To comply with standard EN 610003-2 or IEEE 519, we recommend using the CNW 898 series. The integrated mains filter dampens the very high asymmetrical and symmetrical HF currents caused by the converter.
Benefits
