    3-phase EMC output filters are used to suppress the interference of the VFD output side to the load. It is greatly hulpful to solve the problems of load heating, howling, etc. that are easily generated during long-distance transmission of the variable frequency device. It works better with the reactor. With current rating from 6A, 15A, 30A, 50A, 80A to 1000A, the VFD output filter works at AC 250/440V 50/60Hz to effectively restrain the common-mode interference on the load transmission lines so as to protect the load and extend the load's service life.

    Applications: The EMC output filters are suitable for variable frequency drives, servomotors, frequency converters and and other industrial equipment that require long-distance transmission.

    Tips: Working principle of EMC filter for VFD

    The interference signal has two modes: differential mode and common mode, so the filter for VFD should have attenuation for both types of interference. There are three basic principles:
    1. Take advantage of the characteristics of capacitor - high frequency passing and low frequency isolating, to direct the high-frequency interference currents of the live and neutral lines to the ground (common mode), or direct the high-frequency interference currents of the live line to the neutral (differential mode).
    2. Use the impedance characteristics of the inductor to reflect the high-frequency interference current back to the interference source.
    3. The interference suppression ferrite can be used to absorb the interference signal of a certain frequency band and convert it into heat. Therefore, for the frequency band of a certain interference signal, the appropriate interference suppression ferrite magnetic ring or magnetic beads can be selected and directly placed on the cable that needs filtering.
