Product features
:
Motor drive system C filter is designed based on the electromagnetic interference characteristics of the input side power grid and C, C and other digital equipment when the frequency converter is working. It has excellent differential mode and common mode interference attenuation characteristics, and the effective filtering frequency bandwidth is from to effective While suppressing the electromagnetic interference caused by the frequency converter to the power grid, it can also prevent the electromagnetic interference caused by other interference sources in the power grid to the frequency converter. It is also used in other industrial occasions with strong electromagnetic interference

Precautions during use
:
>The filter and inverter must be installed on the same base plate There must be a low-impedance high-frequency connection between the filter, the frequency converter and the mounting plate
>The filter must be as close as possible to the input terminal of the frequency converter, and generally the distance between the two should not exceed >c< br/> >The filter has a ground terminal, and this terminal must have a low-impedance connection with the filter’s installation rack
>Note that power filters dedicated to frequency converters generally have higher leakage currents (this is because It is inevitable to improve the low-frequency filtering effect of the filter). For safety reasons, the filter must be strictly grounded.
