Model RSD-300B-12
Description Mean Well 300W Railway certification regulation isolation DC-DC converter - RSD 300 series Mean Well Railway power supply RSD-300 series can meet various requirements of vehicle applications. Compliant with railway certification (EN50155, IEC60571, IEC61373, EN50121-3-2), therefore suitable for vehicles equipped with DC power supply. This power supply has 5G anti vibration capability and a wide operating temperature range of -40 to+70 ℃, with short circuit, overload, output overvoltage, over temperature, and input reverse polarity protection. It also has a built-in current limiting circuit. The RSD-300 has an efficiency of up to 91%, and its semi sealed design provides protection for printed circuit boards, offering basic moisture, dust, and heat dissipation functions. RSD-300 does not require forced air cooling and will still function normally between -40% and+70% ambient temperatures. This Mean Well power supply is suitable for applications in harsh environments and various vehicles equipped with DC power supply. Applications include railways, urban rapid transit systems, subways, buses, leisure trailers, ships and safety systems, DC UPS systems, and telecommunications equipment. Compliant with EN50155 (IEC60571) railway regulations, 2:1 wide input range 4000V DC input/output isolation efficiency up to 91%. Cooling through natural air convection. Built in constant current limiting circuit protection: short circuit/overload/overvoltage/overtemperature/input reverse polarity (not damaged). Powered by 105 ° C long-life electrolytic capacitor, LED indicator light with 100% full load aging test. Wide working range from -40 to+70 ° C. Compliant with IEC60950-1 (LVD), including IEC61373 (impact and vibration), EN50121-3-2 (for EMC), Mean Well DC-DC converter, Mean Well packaged DC-DC converter
