Product Information for MEAN WELL MPM-45-48ST

The MEAN WELL MPM-45-48ST is a high-reliability 45W medical-grade AC/DC power module specifically designed with a screw terminal chassis mount configuration. As detailed in the MPM-45-spec.pdf, this power supply complies with the rigorous IEC/EN60601-1 and ANSI/AAMI ES60601-1 safety standards, featuring 2xMOPP (Means of Patient Protection) insulation. A key characteristic is its ultra-low leakage current (less than 100 µA), making it an ideal choice for BF-type medical equipment that requires safe patient interface. The "ST" version includes integrated terminal blocks and mounting holes, facilitating easy installation without the need for specialized PCB layouts.

Technically, the MPM-45-48ST excels with a 92% typical efficiency and an environmentally conscious no-load power consumption of under 0.1W. The device is built for durability, featuring an operational altitude of up to 4000 meters and a wide temperature range from -30 °C to +80 °C. Equipped with comprehensive protections including short circuit, overload, and over-voltage, and capable of delivering a peak power of 49.5W, it provides a stable and secure 48V DC source. This module is perfectly suited for medical computer monitors, mobile clinical workstations, and diagnostic examination instruments requiring high-voltage, medical-grade power conversion.
