Power Feed Through Filters F.LL.DH-F.LL.DU series Single line - high performance This wide range of feed-through filters provide excellent RFI attenuation up to GHz frequency levels. They are an economical alternative to dedicated filter units, where multiple input or output power lines require suppression. Particularly suitable for use in screened rooms, high frequency welding equipment, power supplies and telecom systems. Due to the high capacitance values of these filters, protective measures (e.g. protective earthing) in accordance with equipment / system regulations are required. • Current ratings from 16A to 300A • Excellent attenuation up-to 1GHz • Wide choice of performance options • Rugged resin sealed construction • Lock-nut or flange-mounting Mechanical Specifications Electrical Specifications Manufacture: metal case sealed with plastic cover; Rated voltage (VR): see table mounted with rectangular flange (F.LL.DH) Rated current (IR): referred to room temperature = 40°C or metric nut M32 (F.LL.DU). Voltage test (2S.): see table Climatic category: GPC (40/085/56); Connections: threaded bar with metric nut M6 (up to 63A), Temperature range: -40°C to +85°C M8 (100A), M10 (200A), M12 (300A); Note: on screwing the cable to the filter, the lock nut must be held in position to avoid a torque to the threaded bar inside the filter.
