Product Information for MEAN WELL MPM-05-3.3

The MEAN WELL MPM-05-3.3 is a high-density, 5W AC/DC encapsulated medical grade power supply designed to deliver superior performance in a miniature 1.8" x 1" footprint. Engineered for PCB mounting, this module provides a stable 3.3V output and adheres to the stringent 2xMOPP (Means of Patient Protection) safety standards. Its ultra-low leakage current of less than 80 µA and BF-ready compliance make it a top-tier choice for medical examination instruments, portable diagnostic tools, and clinical monitors where patient safety is paramount.

Beyond its safety credentials, the MPM-05-3.3 is built for durability and efficiency in Class II configurations without a functional ground. The interior is fully potted to enhance heat dissipation and provide 5G anti-vibration capabilities, ensuring a long operational lifespan of over 48,000 hours. It operates reliably in extreme environments ranging from -40 °C to +85 °C and features an impressive standby power consumption of less than 0.075W, supporting "green" energy initiatives while maintaining high EMC performance for sensitive medical electronics.
