Appliance inlet filters with ground choke

Power entry module series extended with versions including a ground line choke, designed for suppressing high-frequency interference on the ground conductor. Additionally, the new variants have a bigger X-capacitor for better symmetrical attenuation. The C20F filter series combines an IEC C20 appliance inlet with a high-quality mains filter. The particularly wide metal flange makes contact with the housing surface over a large area, thus enabling optimum filtering and shielding.

New variants of the C20F appliance inlet filters are equipped with a ground choke. The line filters have a second choke on the earth conductor in addition to the current-compensated choke on the pole and neutral conductor. The ground choke is located between the device plug and the filter output. Placing it directly at the mains input ensures that possible high-frequency interference currents on the earth conductor cannot bypass the filter via the housing. Medical filters in particular (no Y-capacitors) benefit from improved asymmetrical attenuation in the higher frequency range due to the ground choke.
