Information on the MEAN WELL MPM-20-3.3

The MEAN WELL MPM-20-3.3 is a high-density 14.9W encapsulated AC/DC medical power module, as described in the MPM-20-spec.pdf file. It is specifically engineered to comply with the most stringent medical safety requirements, featuring 2xMOPP isolation and an ultra-low leakage current of less than 80 µA. This makes the unit an excellent choice for BF-rated patient contact equipment. The fully encapsulated design not only protects against external contaminants but also incorporates a potting compound that enhances heat dissipation and provides 2G anti-vibration capability, ensuring long-term durability in clinical settings.

This "Green Medical" solution is characterized by an extremely low no-load power consumption of less than 0.1W, promoting energy efficiency in healthcare devices. Its Class II double insulation design eliminates the need for a functional ground connection, simplifying system integration in compact medical housings. Providing a stable 3.3V output, the MPM-20-3.3 is perfectly suited for powering low-voltage digital circuits and sensors within portable medical monitors and workstations, maintaining peak performance across a wide temperature range of -35°C to +85°C.
