Information for MEAN WELL MPM-90-48ST

The MEAN WELL MPM-90-48ST is a high-density 90W AC/DC medical grade power module equipped with integrated screw terminals for versatile chassis-mount installation. As detailed in the MPM-90-spec.pdf, this model features a 2xMOPP (Means of Patient Protection) safety rating and an ultra-low leakage current of less than 100µA, making it a premier choice for BF-rated patient contact medical equipment. The screw terminal design allows for rapid field wiring and secure connections, facilitating the development of portable medical instruments and mobile clinical workstations without the need for PCB-level integration.

This power supply stands out for its exceptional energy efficiency of up to 92.5% and a no-load power consumption of under 0.1W, significantly reducing thermal waste in sensitive healthcare environments. It provides a stable 48V output with a peak power capability of 99.8W for up to 10 seconds, ensuring critical overhead for motor-driven medical components or large displays. Certified for operation at altitudes up to 4000 meters and featuring silent fanless cooling, the MPM-90-48ST offers a reliable, low-maintenance power solution for high-resolution medical monitors, diagnostic systems, and specialized laboratory instruments.
