## Summary description

MEAN WELL MPM-45-5ST is a 45 W indoor power adapter designed for universal applications. It accepts an input voltage range of 80–264 V and provides medical-grade safety with EN/UL 60601 certification and 2xMOPP isolation. The compact black unit (52 × 109 × 33.5 mm) is RoHS compliant and suitable for embedded or equipment power where reliable, certified low-voltage supply is required.

## Long description

MPM-45-5ST is a 45W AC/DC PCB-mount medical-grade power adapter designed for compact equipment and embedded applications. The adapter accepts a wide input voltage range (80–264VAC), delivers high conversion efficiency (up to 92.5%), and meets EN/UL 60601 safety standards with 2xMOPP isolation and low leakage current. Its small dimensions and low no-load consumption make it suitable where space and standby power losses are critical.
Advantages
The power adapter offers high efficiency up to 92.5%, very low no-load power consumption (\<0.1W), and robust isolation (4kVAC) with Class II double insulation (no FG). It is designed for good thermal dissipation, high EMC performance, and anti-vibration resistance (2–5G by model). The unit is EN/UL 60601 certified for medical applications and provides 2 x MOPP safety protection.
Suitable for
 Medical devices and equipment requiring EN/UL 60601 compliance
 Embedded systems and PCB-mounted power solutions
 Compact desktop or portable equipment with limited enclosure space
 Applications needing low standby power and high EMC immunity
