-
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
