Filters
Filters are required for filtering motor input voltage in frequency converter applications. Filtering extends motor service life, lowers the temperature and ensures better reliability of operation. The transformers are used in different kinds of industrial, construction, energy technology and marine applications, such as electric motors, compressors or cooling systems.
Our selection includes DU/dt and Sine filters. The features, dimensions, structure and mounting options of the filters can be tailored according to the customer’s objectives and needs. We are continuously developing our design, certification and manufacturing methods in order to respond to increasingly demanding challenges.
Sine filters
The Sine filters are used for filtering high frequency interference in the input voltage of a motor in order to achieve cleaner sinusoidal voltage. High frequency interference is a great risk for motor coil insulation standard selection of different current ranges ensures an optimal filter choice.
The features, dimensions, structure and mounting options of the filters can be tailored according to the customer’s objectives and needs.
