    FXMP25. Line reactors The FXMP25, in common with all naturally commutated SCR drives, causes voltage notches at the input supply terminals. To avoid disturbances with other equipment using the same supply, the addition of external line inductance is strongly recommended in order to restrict the depth of notches imposed.
