The u700 filter has been specifically designed to overcome EMC problems inherently caused by the
DC drives in motor drive applications especially where size constraints are an issue.
This new range of micro size filters has high attenuation factors and high current capabilities without having a large profile. Motor drives electronically switch high voltages and currents to improve efficiency and reduce acoustic noise in the motor. This switching generates high levels of Radio Frequency interference (RFI) and high-energy surges, which can disturb or damage other electronics circuits.
The u700 series is a two-stage design in 2, 3 or 4 line formats, with output line inductors to suppress dI/dT switching currents that are harmful to capacitors that are present on the supply.
The filter components are housed in compact chassis mounted, aluminum enclosures that allows side or base mounting, it is then encapsulated in a polyurethane potting compound to give excellent protection against shock and vibration. These combinations give a total range of over 30 filter applications.
