Information about the MEAN WELL LOP-500-54

The MEAN WELL LOP-500-54 is a specialized 500W high-voltage power supply featuring an ultra-slim 5" x 3" open frame design. This 54V model is engineered specifically for power-intensive PoE (Power over Ethernet) systems and advanced network switches that require a stable, high-voltage rail to minimize transmission losses. With an impressive efficiency of up to 95.5%, it minimizes heat dissipation within tight 1U enclosures, delivering 324W under natural convection and reaching its full 502.2W capacity with forced air cooling. Its 30.5mm low-profile height makes it an essential component for modern, high-density communication infrastructure.

Beyond its electrical performance, the LOP-500-54 is built to meet the most stringent global safety standards, including medical 2xMOPP isolation and a low touch leakage current of under 70µA. This makes it a versatile choice not only for IT and telecom but also for BF-rated medical applications and industrial controls. It is designed to thrive in challenging environments, certified for altitudes up to 5000 meters and featuring a wide operating temperature range of -40 to +80 °C. Supported by Overvoltage Category III (OVC III) compliance and a 3-year manufacturer warranty, it offers a reliable, long-term power solution for mission-critical hardware.
