EMV-/Netzfilter

What is an EMI Filter?

An EMI filter, or electromagnetic interference filter, is an electronic passive device used to suppress conducted interference present on a signal or power line. EMI filters are used to suppress interference generated by the device, or by other equipment, to protect a device from electromagnetic interference signals present in the environment. Most EMI filters consist of components that suppress differential and common mode interference.

To protect and optimize equipment, Enerdoor EMI/ RFI filters provide solutions in three product categories: single-phase, three-phase, and three-phase plus neutral filters.

Types of EMI Filters

Enerdoor single-phase filter series offers a current range from 1 to 100A with nominal voltage up to 690 Vac. These filters guarantee high attenuation with compact mechanical dimensions.  Available with various connections such as: IEC plugs, fastons, terminal blocks, cables, and screws. Additional DIN rail mounting provides fast and easy installation into the enclosure.  For all models, a dedicated low leakage current solution is available for medical applications.

Enerdoor three-phase filter series offers a current range from 1 to 3000A with nominal voltage up to 690 Vac. This series is one of the largest and most complete for solutions in the industrial automation industry. These filters provide high attenuation in a compact case with low leakage currents and are suitable for several industries.  

Available with terminal block, cable, screw and bus bar connections and with finger safe protection for screw and bus bar options.  DIN rail mounting provides fast and easy installation into the enclosure.  Enerdoor offers solutions in traditional TN and TNS networks and in specific applications such as IT power line configurations. Customized voltage, current, connection, and attenuation solutions are available to satisfy various application needs.

Enerdoor three-phase plus neutral filter series offers a current range from 1 to 2000A with nominal voltages up to 600 Vac. This series provides high attenuation in a compact case with low leakage current and is suitable for several industries.  Available with terminal block, cable, screw and bus bar connections and with finger safe protection for screw and bus bar options.  DIN rail mounting provides fast and easy installation into the enclosure.  Customized voltage, current, connection, and attenuation solutions are available to satisfy various application needs.
