  • L type filters - lowpass filters are designed to suppress radio interference in the frequency band 0.15 - 30MHz

  • the filters are attached to a metal frame connected to the skeleton with two M4 screws (from 10A with screws M5)

  • the filters are connected in such a way that alignment of the suppressed (inlet) and unsuppressed (outlet and all other) wires does not occur
