The RSDH-300-24 is a high-reliability, 300W enclosed-type DC-DC converter designed to supply a stable 24V DC working voltage from an ultra-high DC input. It operates over an extremely wide 6:1 input range of 250Vdc to 1500Vdc, features a typical efficiency of up to 90%, and provides a rated current of 12.5A. Key features include a fanless design with free air convection cooling, 4KVac reinforced I/O isolation, and a wide operating temperature range of -40°C to +80°C. The unit is equipped with comprehensive protections against short circuits, overload, over-voltage, and DC input reverse polarity. With its ability to operate at altitudes up to 5000 meters, it is ideal for demanding applications such as photovoltaic power generation, renewable energy systems, and industrial control systems.
