Product Name:Three-phase input & output filter
Category:Power Electronics
This three-phase input filter is characterized by favorable interference rejection capability. It is mainly used in the data processing system, telecommunication system, transducer and power supply cleaning which requires the application of strong interference suppressor. 
The output AC reactor is mainly used for the smoothing filtering. By reducing the transient voltage dv/dt, it extends the service-life of the electrical machine. This equipment is also applied to reduce the noise of the electrical machine, the eddy-current loss and the leak current caused by the output of the higher harmonic. Moreover, it is also employed to protect the power switching components inside the inverter.

Based on different operating frequency, clients can reasonably choose the magnetic materials (such as silicon steel sheet, ferrite, amorphous iron core and magnetic powder core) as the raw material of this product. 
The excellent performance of this equipment is due to the foil winding structure, low DC resistance, strong resistance to electromagnetic force and good overload ability in short time. F and above class composite insulating materials are used to ensure the reliable performance of the output AC reactor under harsh working conditions; The advantages of the design includes low magnetic flux density, high linearity and good overload capacity. Moreover, the cooperation of the design and the vacuum pressure impregnation process ensures the low noise of the product.
