This module is a fixed 50Hz notch filter, with two-stage notch, better notch depth and higher Q value. which is specifically applied to the notch frequency of 50Hz in power system. A large number of filter capacitors are used for the notch of kHz level above signal acquisition, with good filtering characteristics.
Special attention: due to the tolerance of capacitance and resistance, the center frequency of 50Hz may shift, and the measured value is within plus or minus 3Hz
