Mean Well MDR-40-24

24‑V 40‑W Compact DC‑DC Buck Converter – MDR‑40‑24

The Mean Well MDR‑40‑24 is a rigorously tested DC‑DC step‑down converter designed for the most demanding industrial, telecom, and data‑center environments. With a fixed 24 V output and a maximum power of 40 W, it converts a wide 44‑84 V DC input to a clean, highly regulated supply while maintaining peak efficiency. The module features a robust over‑current &over‑temperature protection scheme, EMI suppression, and a proven 4‑phase synchronous‑rectifier topology, ensuring reliable operation even in high‑noise, high‑temperature deployments.
