Note:1.Wind the cable 4 or more times in the same
direction in each phase. (A greater effect is
produced as the winding times increase.)

more filters in series and wind the cable in the
same direction in each phase.
3.This filter can also be used on the output side
as on the input side. The winding on the output
side should be within 3 turns.
