Power adapter Mean Well MPM-45-24ST 45 W indoor 24 V, input 80–264 V, black, 52×109×33.5 mm

MPM-45-24ST is a 45 W AC/DC PCB-mount medical-grade power adapter that provides a 24 V DC output and accepts a wide input range of 80–264 VAC. The unit is compact and high-density, with low no-load consumption (<0.1 W) and a stated efficiency up to 92.5%. It meets medical safety requirements with double insulation, 2×MOPP isolation and compliance to IEC/EN 60601-1 (including ANSI/AAMI A/ES60601-1 variants), RoHS conformity, and high EMC performance. The adapter is intended for indoor use and comes in a compact black housing sized for space-constrained equipment.

Advantages

The Mean Well MPM-45-24ST combines a small footprint with high power density and efficient operation, reducing wasted energy thanks to high efficiency and very low standby consumption. Its medical-grade design provides 2×MOPP isolation, low leakage current and 4 kVAC isolation capability for patient-connected applications, while robust EMC characteristics and anti-vibration features improve reliability in equipment installations.

Suitable for

• Medical devices and diagnostic equipment requiring 24 V DC with 2×MOPP isolation
• Embedded systems and PCB-mounted power modules in compact enclosures
• Laboratory instruments and small clinical appliances
• Industrial control modules with strict EMC and safety requirements
