The U300 drive filter has been specifically designed to overcome EMC problems inherently caused by variable speed
drives, especially in applications where size constraints are an issue.
This new range of filters have high attenuation factors and high current capabilities without having a large profile. Variable speed 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 U300 drive filter is a two-stage design in 3 and 4 line formats, with an output damping core for
additional mid-range performance.
The filter components are housed in compact, chassis mounted, aluminum enclosures that allow side or base mounting (except 600A). They are then encapsulated in a polyurethane potting compound to give excellent protection against shock and vibration.
These filters are now available in “Flat Pack” form.
