MeanWell MEAN WELL RSD-300E-48, 25.2 - 46.8 V, 300 W, 48 V, RoHS, 97 mm, 216 mm

To expand its product line of enclosed DC/DC converters, Meanwell offers the RSD series power supplies, which meet a variety of different requirements for vehicle applications, now available in output powers of 300 watts. The RSD-300 series features a 2:1 input voltage range. The RSD series power supplies provide 4000 VDC input/output isolation, 5G vibration resistance, an operating temperature range of -40 to +70 °C, and a low 1U profile (25 mm). Additionally, they are equipped with built-in constant current limiting and protection functions against overload, short circuit, overvoltage, and reverse polarity. With their highly efficient circuit design, the Meanwell RSD series achieves an efficiency of up to 93%. All RSD converters are semi-encapsulated and can operate without forced cooling in ambient temperatures ranging from -40 °C to +70 °C, making them well-suited for harsh environments with high or low temperatures, dust, and moisture. The design of the Meanwell RSD converters complies with ITE standards (IEC 60950-1 and EN 55032) and railway application standards (EN 50155, EN 45545-2, and IEC 60571), making them suitable for all types of vehicle applications, including railways, subways, buses, recreational trailers, ships, etc. For applications requiring double insulation, voltage stability, and industrial facilities such as security systems, DC UPS systems, and telecommunications equipment, the Meanwell RSD series converters also perfectly meet the requirements. Special feature: DC/DC converters.
