## Long description

The MEAN WELL GSM40B12-P1J is an AC-DC medical desktop adapter delivering 12V DC at 3.34A (40W) from an 80–264V AC input. It uses a 2-pin IEC320-C8 input socket and supplies output through a P1J tuning fork plug with outer diameter 5.5 mm, inner diameter 2.1 mm and length 11 mm. The adapter meets EN 60601 medical safety requirements with 2xMOPP isolation, is Class II and RoHS compliant. Its compact dimensions (50 mm × 125 mm) and weight of 281.8 g make it suitable for medical and professional devices requiring a reliable low-voltage supply.
Advantages
The GSM40B12-P1J provides a stable 12V/3.34A output with built-in medical-grade isolation (EN 60601, 2xMOPP) and Class II double insulation, reducing risk in clinical environments. Its wide input range (80–264V AC) allows global use without an external converter, while the standardized P1J tuning fork plug (5.5 × 2.1 × 11 mm) and IEC320-C8 inlet simplify installation and replacement. Compact size and RoHS compliance add to its suitability for regulated equipment.
