FMBC EP 3-Phased Double Stage Filters Schurter FMBC EP 3-Phased Double Stage Filters provide high performance in a compact package, ideally suited for space-constrained machine and industrial plant construction. Versions with high nominal voltages are particularly suited for a wide field of applications. The almost cuboidal design makes optimum use of the space in the housing. A double-stage filter built with high-quality components (generously sized film capacitors, chokes with highly permeable cores) provides exceptional broadband filter attenuation. The double-stage filters are also appropriate for applications with particularly high EMC emissions, as is frequently encountered in machine operations. Typical applications include automatic production, motor drives, and industrial plant machinery. These powerful filters are also ideal for modern frequency inverters for motor control.
