Power adapter/inverter MEAN WELL GSM120A15-R7B, 120 W, 15 V output, 80–264 V input

MEAN WELL GSM120A15-R7B is a 120 W AC‑DC medical power adapter/inverter that provides a regulated 15 V DC output at up to 7 A. The unit accepts a wide AC input range of 80–264 V and is built in a compact metal housing (67 × 167 × 35 mm) suitable for industrial and commercial installations. Designed to meet medical safety requirements, it features EN 60601 compliance with 2×MOPP isolation and an AC 3‑pole IEC inlet for secure connection. The adapter is RoHS compliant and supplied in multi‑packs for system integrators and OEM deployments.

Advantages

The adapter offers a stable 15 V output with up to 7 A current capacity and efficient power conversion in a compact metal enclosure. Wide input voltage compatibility reduces the need for additional input conditioning across different regions. Medical‑grade isolation (2×MOPP) and EN 60601 compliance support use in equipment where patient and operator safety are required. The AC 3‑pole IEC inlet simplifies installation and replacement in rack or bench setups.

Suitable for

• Medical devices and diagnostic equipment requiring medical‑grade isolation
• Control panels and automation systems that need stable 15 V DC power
• LED drivers and lighting systems with 15 V input requirements
• Communications and networking equipment in industrial environments

Key specifications

How to use

Install the adapter on a flat surface or inside equipment with adequate ventilation and secure mounting. Connect the AC mains using a compatible 3‑pole IEC mains lead and verify the supply voltage is within 80–264 V. Connect the 15 V DC output to the load using appropriately rated wiring and observe polarity. Allow the adapter to reach operating temperature before loading to full current and avoid placing it near heat sources or in confined spaces without airflow.

Recommendations

For reliable long‑term operation, ensure adequate ventilation, use overcurrent protection on the DC output, and perform periodic inspections of the mains connection. In medical installations, follow applicable EN 60601 installation practices and separation distances to maintain 2×MOPP isolation. Use cabling and fuses rated for at least the maximum output current plus a safety margin.
