SCHURTER’s FMAB NEO single-phase filter series

Filter Series Offers Better Earth Conduction

Jan. 25, 2023
SCHURTER’s FMAB NEO offerings provide a simple solution to filtering critical earth conductor currents.

SCHURTER’s FMAB NEO single-phase filter series now has enhanced asymmetrical attenuation performance in higher frequencies, achieved by adding a ground line choke on the earth conductor. The new filter series offers a simple solution to filtering critical earth conductor currents generated by today’s power conversion technologies, such as those using high-speed switching power supplies, frequency converters and motor drives.

The FMAB NEO offers a second choke on the earth line to better address potential electromagnetic interference. The ground line choke is located between the filter input and output. With the two earth connections at the input and output, the earth connection at the main input is insulated from the housing. This ensures that possible high-frequency interference currents on the earth conductor cannot bypass the filter via the housing.
