Power Adapter MEAN WELL GSM90A48-P1M 90W Input 80-264V Output 48V

The MEAN WELL GSM90A48-P1M is a desktop AC‑DC medical power adapter delivering 48 V DC at up to 1.87 A (90 W). It accepts a wide input range of 80–264 V AC via a 3‑pole IEC inlet, meets medical isolation requirements with EN 60601 and 2×MOPP protection, and uses a 4‑pole DIN output connector. Its compact housing (60 × 145 × 32 mm) and RoHS compliance make it suitable for equipment requiring a stable, certified low‑voltage supply.

Advantages

The adapter provides a regulated 48 V output with up to 90 W power and a broad AC input range (80–264 V), enabling use in diverse mains environments. Compliance with EN 60601 and 2×MOPP ensures required medical isolation and safety for many healthcare applications. The desktop form factor with a standard 3‑pole IEC inlet and a 4‑pole DIN output connector simplifies integration into existing systems. Compact dimensions and RoHS conformity support space‑limited, environmentally conscious installations.

Suitable for

• Medical devices and diagnostic equipment requiring EN 60601-compliant isolated 48 V supply
