## Long description

MPM-45-48ST is a compact 45 W indoor AC/DC PCB-mount medical-grade power adapter with universal input voltage 80–264 VAC and a regulated 48 V output. The unit meets medical safety standards (EN/UL 60601) with 2×MOPP isolation and low leakage current, and is RoHS compliant. Its small footprint and high efficiency make it suitable for professional and industrial devices that require a stable 48 V supply.
Advantages
The adapter delivers high efficiency (up to 92.5%) and very low no-load power consumption (\<0.1 W). It provides reinforced insulation equivalent to Class II (2×MOPP), high EMC performance, 4 kVAC isolation and robust anti-vibration characteristics (2–5 G depending on model). The compact dimensions and effective thermal dissipation simplify integration into space-constrained designs.
Suitable for
Medical equipment and diagnostic devices requiring 2×MOPP isolation
Professional and industrial electronics needing a stable 48 V supply
PCB-mounted power solutions in compact assemblies
