The Ferrocore DE1205-3,1 is a 3-phase EMI/EMC power line filter which provides filtering for Class I, Division 2 and Class II, Division 2 environments. It is designed to reduce the emissions of conducted noise generated by electrical and electronic equipment, such as AC motors, lighting systems, solenoids, transformers, and more. The Ferrocore DE1205-3,1 filter is UL approved and is constructed with a 50A single-point ground. Its line-to-line capacitance value is 40 uF while its line-to-ground capacitance ranges from 200 nF to 1000 nF. The DE1205-3,1 has a maximum operating voltage of 250 Vrms and an impedance of 3.5 ohms @ 1 kHz.
