Mean Well 300W Railway Certified Regulated Isolated DC-DC Converter - RSD 300 Se
The Mean Well railway power supply RSD-300 series can satisfy the various requirements of vehicle applications. Complies with railway certificates (EN50155, IEC60571, IEC61373, EN50121-3-2) making them suitable for use in vehicles that are equipped with DC power source. This Power supply has a 5G anti-vibration ability and a wide range working temperature of -40 to +70℃, with protections for short circuit, overload, output over voltage, over temperature and input reverse polarity, it also has a built in current limiting circuit. The RSD-300 possess up to 91% of high efficiency, it is semi encapsulated for PCB protection, providing the basic function of anti moisture, anti dust and heat dissipation. The RSD-300 can be cooled without forced air and still work between -40% and +70% ambient temperature. This Mean Well power supply is suitable for applications of harsh environment and for all kinds of vehicles that are equipped with DC power source. The applications include railway, metro rapid transit system, subway, bus, leisure trailer, vessel and also security system, DC UPS system, and telecom equipments.
