EMI-Filter CNW 307

Filtercombination (single stage)

Description

The CNW 307 combination filter relieves the supply network by compensating for harmonic reactive power. The harmonic harmonics are reduced to THD < 60 %. This improves the efficiency and relieves the line. The line reactor also limits the occurring line disturbances, such as current peaks and voltage dips of the line. To comply with the EN 610003-2 or IEEE 519 standard, we recommend using the CNW 898 series. The integrated line filter attenuates the very high asymmetrical and symmetrical HF currents caused by the inverter.

Advantages

Compact construction
Different connections (Terminals/cables /bars)
Easy and fast istallation damping of the harmonics
Attenuation of current harmonics
Limintation of inrush currents
Reduction of mains disturbance, current peaks and voltage drops
Increased life time for IGBT‘s
Low noise

Typical applications

Applications: Interference suppression of frequency converters with IGBT’s and reduction of harmonics PFC (Power Factor Correction) and commutation (current conduction between thyristors) with fast switching semiconductors.
