## Summary description

Mean Well MPM-45-5 is an indoor power adapter with 45 W output designed for universal DC power supply applications. It accepts 80–264 V AC input and comes in a compact black enclosure (52 × 87 × 29.5 mm). Suitable for powering electronic devices and small equipment where a reliable indoor 45 W adapter with RoHS compliance is required.

## Long description

Mean Well MPM-45-5 is an indoor 45 W AC/DC power adapter designed for compact, universal DC power supply applications. The unit accepts a wide input voltage range of 80–264 V AC and is housed in a black enclosure measuring 52 × 87 × 29.5 mm. Engineered for high efficiency and low standby consumption, this adapter is intended for powering electronic devices and small equipment where a reliable, medically informed design and RoHS compliance are required.
Advantages
The adapter delivers up to 45 W from a compact, high-density PCB-mount format with a maximum efficiency of up to 92.5% and low no-load power consumption below 0.1 W. It provides double insulation construction (Class II, no FG), outstanding thermal dissipation and 4 kVAC isolation between primary and secondary for improved safety. The design meets medical-grade requirements with 2 x MOPP insulation and ultra-low leakage current, and it includes high EMC performance and anti-vibration capability suitable for indoor installations.
Suitable for
 Powering small electronic devices and modules that require a stable 5 V DC supply
 Embedded and PCB-mounted applications in confined enclosures
 Medical devices and diagnostic instruments requiring 2 x MOPP isolation and low leakage
 Equipment operating from a wide AC mains range (80–264 V AC)
Key specifications
