Power Adapter MEAN WELL GSM220A12-R7B 220W 12V Input 80-264V

The MEAN WELL GSM220A12-R7B is a desktop AC-DC medical power adapter with Active PFC, designed to deliver a stable 12V DC output at up to 15A (220W). It accepts a wide AC input range from 80 to 264V via a 3-pin IEC320-C14 socket and provides a DIN 4-pin plug with lock for the DC connection. Constructed to meet medical safety requirements, it features EN60601 compliance with 2xMOPP isolation and is a Class I device. The adapter has compact dimensions (85 mm × 210 mm × 46 mm) and is RoHS certified.

Advantages

The adapter integrates Active PFC for improved power factor and stable operation across the specified input range. Medical-grade safety with EN60601 and 2xMOPP isolation supports use in equipment requiring dual means of patient protection. The locked DIN 4-pin output ensures a secure connection, while the compact form factor allows installation in space-constrained environments. RoHS compliance confirms reduced hazardous substances.
