Information on the MEAN WELL MPM-20-12
The MEAN WELL MPM-20-12 is a high-density 21.6W encapsulated AC/DC medical power module, detailed extensively in the MPM-20-spec.pdf document. It is specifically designed to meet the rigorous safety standards of the healthcare industry, featuring 2xMOPP isolation and an ultra-low leakage current of less than 80 µA. These characteristics allow the unit to be integrated into Type BF patient-contact equipment with confidence. Its miniature footprint and fully encapsulated design provide robust protection against dust and moisture while enabling 2G anti-vibration capability, ensuring stable performance in demanding clinical environments.
This "Green Medical" power supply stands out with its exceptional efficiency of 85.5% and a standby power consumption of less than 0.1W, significantly reducing energy waste in medical systems. The Class II insulation level eliminates the need for a functional ground, offering designers more flexibility during the PCB layout phase. Built to withstand harsh conditions, it operates reliably within a broad temperature range of -35°C to +85°C. Whether used in portable medical monitors, diagnostic tools, or clinical workstations, the MPM-20-12 provides a stable 12V output combined with comprehensive protection against short circuits, overloads, and over-voltages.
