描述

The 800859-SF is a book-style EMC/RFI filter designed for three-phase power distribution systems in inverters and power drive systems. It features a slim space-saving housing with solid safety connector blocks or optional wire output connections, providing excellent attenuation performance across a wide range of current ratings from 7 A to 250 A at 50°C. The filter operates at DC to 60 Hz with maximum continuous operating voltages of 3×520/300 VAC for standard versions, delivering power loss ranging from 9 W to 79 W depending on the current rating. Leakage current specifications vary from 2.0 mA to 3.5 mA at 520/760 VAC/50 Hz, with weights ranging from 1.0 kg to 19 kg. This filter is widely used in industrial power conditioning applications where EMC compliance and reliable filtering of harmonic distortion are essential for protecting sensitive equipment and ensuring regulatory compliance.
