Information about the MEAN WELL LOP-500-48

The MEAN WELL LOP-500-48 represents the peak of efficiency in the LOP series, boasting an ultra-high efficiency of up to 95.5%. This 48V power supply is housed in a compact 5" x 3" open frame with a remarkably low profile of 30.5mm, making it the perfect solution for 48V bus systems, PoE (Power over Ethernet) applications, and advanced telecommunications infrastructure. Its high-voltage output allows for reduced cable losses over long distances, while its dual-cooling design provides 321.6W under natural convection and a full 504W with forced air, ensuring reliable performance in high-density 1U cabinets.

Engineered for mission-critical reliability, the LOP-500-48 features multi-field global certifications, including medical 2xMOPP isolation and low leakage current for BF-type medical equipment. It is uniquely qualified for industrial environments due to its Overvoltage Category III (OVC III) compliance, which allows for a more direct and cost-effective connection to the AC mains. Designed to withstand extreme conditions, it operates flawlessly at altitudes up to 5000 meters and across a wide temperature range from -40 to +80 °C. This unit combines high power density with a robust safety profile, all backed by a 3-year manufacturer warranty.
