FN3120
High-Performance EMC/RFI Filter for Drives
3-Phase Filters FN3120
High-Performance EMC/RFI Filter for Drives
- High performance filter for extremely noisy applications
- Significantly improves the reliability and immunity of installations
- Enables compliance with Class B limits even with very long cables
Features and Benefits
High-performance filter for mainly indus- trial motor drive applications with extremely high noise levels, providing sufficient interference suppression to achieve Class B even with very long motor cables (e.g. machine tools with up to 12 axes with ~10 to 20 m cables each)
Broadband attenuation performance and exceptional saturating resistance ensure reliable interference suppression
FN 3120 operated on the mains input of machines or equipment contributes significantly to the reliability and immunity by offering protection against conducted interference phenomena coming from the environment
Solid, touch-safe terminal blocks offer sufficient contacting cross section according to the EN 60204-1 installation standard, which is very common for industrial equipment like machine tools
Compact dimensions and light weight design with good accessibility for automatic and hand tools guarantee a simple time and space-saving installation
Typical Applications
Mainly industrial equipment, machinery and machine tools such as printing machines, packaging machines, extruders, wood working machines, milling and drilling machines, laser cutting machines, welding machines, robotics, conveyors, assembly lines, pumps, oil production, chemical and mining industry, etc. The filters are ideal for most motor drive applications and particularly for regenerative drives with suitable line reactor or LCL filter.
