Mechanical Dimension

Railroad facility filters are mainly used to suppress electromagnetic interference transmitted along the auxiliary power supply system of high-speed railroad locomotives. It is characterized by high reliability, high filtering performance, high insulation withstand voltage, long operation cycle, wide temperature range, and can work in high altitude, high humidity and heat areas, which can assist all kinds of electronic instruments and equipment in high-speed railroad locomotives to pass the relevant railroad industry EMC standards such as EN 50121-3-2-2017, GB/T 24338.4-2018 and so on.
