Information about the MEAN WELL MPM-65-48ST

The MEAN WELL MPM-65-48ST, as detailed in the MPM-65-spec.pdf, is the screw terminal version of the high-performance 48V medical AC/DC power module. Designed for chassis mounting, this unit offers integrated mounting ears and secure terminal blocks, providing an ideal solution for clinical equipment where internal PCB space is limited or field-serviceability is required. It features full 2 x MOPP (Means of Patient Protection) compliance and maintains an exceptionally low leakage current of <100 µA, fulfilling the highest safety requirements for BF-rated patient contact medical devices. This makes it a premier choice for high-voltage medical diagnostic tools and complex clinical workstations.

A core strength of the MPM-65-48ST is its 92% typical efficiency paired with a no-load power consumption of less than 0.1 W, ensuring minimal energy waste and heat dissipation within enclosed systems. The unit is engineered for extreme reliability, certified for operation at altitudes up to 4000 meters and featuring 5G anti-vibration resistance to withstand the rigors of mobile medical hardware. With its 71.5 W peak power capacity to handle transient loads and built-in protections against overvoltage and thermal issues, it provides a stable 48V power source for sensitive healthcare electronics and automated clinical laboratory monitors.
