The REL/025/M filter has been specifically designed to overcome EMC problems inherently caused by the
UPS System application, 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. UPS Systems electronically switch high voltages and currents to improve efficiency and reduce losses in the system. This switching generates high levels of Radio Frequency interference (RFI) and high-energy surges, which can disturb or damage other electronics circuits.
The REL/025/M series is a two-stage design in a 2 line format, 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.
