RSD-200 series (200W Enclosed Type Railway DC/DC Converter)

After the launch of RSD-100 series (100W) and RSD-150 series (150W), MEAN WELL further expanded their second generation of enclosed type single output DC/DC converter and introduced RSD-200 series (200W), to fulfill the various requirements of vehicle applications. Featuring with 2:1 (±40%) wide input range and 4000VDC input/output isolation, RSD-200 series are characterized by 5G anti-vibration ability, wide range working temperature of -40~+70℃, protections for short circuit, overload, output over voltage, over temperature, and input reverse polarity, as well as built-in constant current limiting circuit and 40mm low profile design (1U compliance)…etc.

With up to date high efficiency circuit design, RSD-200 series possess up to 91% of high efficiency. All series are semi-encapsulated for PCB protection to provide the basic ability of anti-moisture, anti-dust, heat dissipation as well as anti-vibration. Therefore, they can be cooled without any forced-air but still work between -40℃ to +70℃ ambient temperature, which perfectly fit in with the applications of harsh environment. The design of these new converters are refer to ITE standards (IEC60950-1 and EN55022) and also comply with railway certificates (EN50155, IEC60571, IEC61373, EN50121-3-2), so that they are suitable to be used in all kinds of vehicles that equipped with DC power source. The applications include railway, metro rapid transit system, subway, bus, leisure trailer, and vessel...etc. In addition, along with external batteries as the energy source, they are also suitable for harsh industrial installations that concern about dust and moisture, such as security system, DC UPS system, and telecom equipments…etc.
