Fuente de alimentación MEAN WELL GSM40B48-P1J 40W 48V 80–264V

The MEAN WELL GSM40B48-P1J is a compact AC-DC medical desktop adapter that delivers 48 V DC at 1.84 A (40 W) from a universal 80–264 V AC input. It features a 2‑pin IEC320‑C8 input socket and a P1J tuning fork output plug (outer diameter 5.5 mm, inner diameter 2.1 mm, length 11 mm). The adapter meets EN 60601 requirements with 2xMOPP isolation and is a Class II device suitable for medical equipment and other applications that require a reliable low-voltage supply.

Advantages

Provides a stable 48 V / 1.84 A output with 40 W rated power in a compact housing (approximately 50 mm × 125 mm) and low weight (about 300 g). Universal input (80–264 V AC) allows worldwide use without an external converter. Compliance with EN 60601 2xMOPP and Class II insulation increases safety for medical applications. RoHS compliance ensures reduced hazardous substances.

Suitable for

• Powering medical desktop devices that require 48 V DC with medical-grade isolation
• Laboratory equipment and test benches needing a compact 40 W adapter
• Industrial or commercial electronics where a P1J (5.5 × 2.1 mm) tuning fork plug is required
