Product Information for MEAN WELL MPM-45-48

The MEAN WELL MPM-45-48 is a high-density 45W AC/DC medical-grade power supply specifically engineered for PCB-mount applications. As detailed in the MPM-45-spec.pdf, this module provides superior safety performance by adhering to IEC/EN60601-1 and ANSI/AAMI ES60601-1 standards, featuring 2xMOPP (Means of Patient Protection) isolation. It is uniquely characterized by its ultra-low leakage current of less than 100 µA, making it an ideal candidate for BF-rated medical devices that require safe, direct contact with patients in clinical environments.

In addition to its safety profile, the MPM-45-48 is recognized for its high efficiency of 92% and an environmentally friendly no-load power consumption of under 0.1W. Its compact footprint does not compromise on power, offering a peak capacity of 49.5W for up to 10 seconds to handle startup surges. Designed for longevity and stability, the unit operates across a wide temperature range from -30 °C to +80 °C and is encapsulated for anti-vibration protection up to 5G. This makes it a primary choice for demanding medical monitors, portable diagnostic equipment, and mobile clinical workstations where reliable 48V DC power is essential.
