Filter combination (single stage)
DESCRIPTION
The CNW 307 combi filter relieves the supply network by compensating the harmonic reactive power. The harmonics are reduced to THD < 60 %. This improves efficiency and reduces the load on the line. The mains choke also limits the mains interference that occurs, such as current peaks and voltage dips in the mains. To comply with the EN 610003-2 or IEEE 519 standard, we recommend using the CNW 898 series. The integrated mains filter attenuates the very high asymmetrical and symmetrical HF currents caused by the inverter.
ADVANTAGES
- Compact design
- Different connections (Terminals/cables /bars)
- Easy installation
- Attenuation of current harmonics
- Limitation of inrush currents
- Reduction of mains disturbance, current peaks and voltage drops
- The increased life time for IGBTs
- Low-noise
TYPICAL APPLICATIONS
Applications: Interference suppression of frequency converters with IGBTs with simultaneous reduction of harmonics PFC (Power Factor Correction) and commutation (current transition between thyristors) in fast-switching power semiconductors.
Reduction of THD values (Total Harmonic Distortion).
