Single-phase mains filter

Single-phase mains filter for interference free operation

REO single-phase mains filters achieve the highest possible damping thanks to powerful chokes.

The single-phase mains filters are available as one-stage or two-stage filters and as a result enable compliance with the EMC guidelines in relation to the limit values for your application.
