RFI Filters
Enerdoor manufacture a wide range of UL recognised, RFI Filters which are made with high quality and come with a five year warranty. RFI (radio frequency interference) is an electronic emission that is designed to break down, diminish or prevent electrical circuit performance.
A large range of devices can produce radio frequency interference, these include: relays, motors, computing devices, work processors, electronic printers, medical equipment and industrial controls.
Single Phase RFI Filter Models
The 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.
