Information about the MEAN WELL LOP-500-12

The MEAN WELL LOP-500-12 is a state-of-the-art 500W low-profile open frame power supply designed for high-density applications where space is at a premium. Featuring a compact 5" x 3" footprint and an incredibly slim 30.5mm profile, this unit delivers a remarkable power density of 27.8W/in³. One of its most striking features is its versatility in cooling, capable of providing a solid 321.6W under natural convection and reaching its full 500.4W potential with forced air cooling. This makes it an ideal choice for ITE, industrial control, and home automation systems that require robust performance in a minimalist form factor.

Beyond its power metrics, the LOP-500-12 stands out for its medical-grade safety profile, featuring 2xMOPP isolation and extremely low leakage current (less than 70µA), making it suitable for BF-rated medical devices. It is engineered to withstand harsh environments, operating reliably in temperatures ranging from -40 to +80 °C and altitudes up to 5000 meters. With Overvoltage Category III (OVC III) compliance and a high efficiency of up to 92%, this power supply ensures long-term reliability and energy savings for Class I or Class II installations, backed by a comprehensive 3-year manufacturer warranty.
