Information for MEAN WELL MPM-05-3.3

The MEAN WELL MPM-05-3.3 is a high-density, 5W AC/DC encapsulated type power supply module engineered for high reliability in medical applications as detailed in MPM-05-spec.pdf. Housed in a miniature 1.8" x 1" footprint, it is an ideal solution for compact PCB layouts. Its strict adherence to 2xMOPP (Means of Patient Protection) and an ultra-low leakage current of less than 80 µA ensures safe operation in medical devices with direct patient contact (BF rating).

Engineered for long-term stability, the MPM-05-3.3 utilizes internal potting to facilitate superior heat dissipation and provide 5G anti-vibration durability. This Class II isolation device requires no functional ground, simplifying its integration into mobile clinical workstations or portable diagnostic tools. With a no-load power consumption below 0.075W and a broad operating temperature range of -40 °C to +85 °C, this module delivers exceptional "green" efficiency and stable performance for sensitive medical electronics.
