Information about the MEAN WELL LOP-400-36

The MEAN WELL LOP-400-36 is a sophisticated 400W low-profile open frame power supply designed to meet the high-voltage requirements of modern industrial and medical systems. Featuring a standard 5" x 3" footprint and an incredibly slim 27.5mm height, this unit provides a high power density of 24.6W/in³, making it ideal for integration into shallow 1U racks and compact control panels. It is engineered for global versatility, supporting a universal 80-264VAC input and maintaining Over Voltage Category III (OVC III) compliance, which allows for a safer and more cost-effective direct connection to the primary building wiring.

A standout feature of the LOP-400-36 is its comprehensive multi-standard certification, covering Medical (2xMOPP), Industrial (61558-1), and Household (60335-1) safety regulations. With an exceptionally low leakage current of less than 70µA, it is fully optimized for BF-rated medical devices. The power supply offers superior thermal management, delivering 252W under natural convection and reaching its maximum 403.2W output with forced-air cooling. Furthermore, its 150% peak load capacity for 3 seconds ensures that the system can reliably handle temporary power surges required by high-performance automation and telecommunication equipment.
