The Mean Well DDR-240B-48 is a high-performance isolated DIN Rail DC-DC converter designed to convert 16.8-33.6V DC input into a regulated 48V DC output. Delivering up to 5A of continuous output current and 240W of output power, it is ideal for industrial automation, railway systems, telecommunications, renewable energy, and control panel applications.

Featuring 4kV DC input-to-output isolation, the DDR-240B-48 provides enhanced protection against electrical noise and ground loops, ensuring safe and reliable operation in demanding environments. Its 90% high efficiency minimizes power losses while maintaining stable output with 1% load regulation.

Designed for DIN rail mounting, the converter is housed in a compact industrial enclosure and operates reliably across a wide temperature range from -40 C to +70 C. It complies with numerous international industrial and railway standards, making it suitable for mission-critical installations where reliability and safety are essential.
