Schurter is expanding its range of block filters for single-phase systems with the new FMAB NEO series. This range of single-phase filters combines a compact design with a high level of performance. The use of large X capacitors permits high symmetrical attenuation.
Symmetrical interferences can occur because of phase-angle controllers or semi-conductor relays, for example. When the power semiconductors switch, they generate interference currents between the phase conductor and the neutral conductor. These are known as symmetrical interferences, which the X capacitors positioned between these conductors can help reduce effectively. The new filters have a shiny steel housing with a closed filter base, thus being effectively and completely shielded, no matter the way they are going to be mounted. They are particularly suitable for equipment with high symmetrical interferences, but also medical equipment and household appliances.
