Power Adapter Mean Well GSM25B24-P1J 25W 24V Input 80-264V

The Mean Well GSM25B24-P1J is an AC‑DC medical desktop adapter supplying 24 V DC at 1.04 A (25 W). It accepts a wide input range of 80–264 V AC and features a 2‑pin IEC320‑C8 input socket. The output connector is a P1J tuning fork plug with an outer diameter of 5.5 mm, inner diameter of 2.1 mm and a length of 11 mm. The adapter is certified to EN 60601 with 2×MOPP isolation and is Class II, suitable for medical and professional equipment requiring a compact, regulated 24 V supply.

Advantages

The GSM25B24-P1J offers a compact 25 W power solution with wide input voltage compatibility (80–264 V), RoHS compliance, and medical‑grade safety by meeting EN 60601 with 2×MOPP isolation. Its standardized IEC320‑C8 inlet and common 5.5 × 2.1 mm P1J plug simplify installation and replacement in existing systems. The Class II design eliminates the need for protective earth, reducing wiring complexity in regulated environments.

How to use

Connect the adapter to mains power using a compatible IEC320‑C8 mains lead. Plug the P1J tuning fork connector into the device’s 5.5 × 2.1 mm DC input socket, ensuring correct polarity and a secure fit. Verify that the device requires 24 V DC and does not exceed 1.04 A current draw. After connection, power the mains supply; the adapter will provide a regulated 24 V output suitable for powering the target equipment.

Recommendations

Use only with devices specified for 24 V DC and within the 1.04 A current rating. For medical applications, follow applicable installation and grounding practices and consult device documentation to confirm compatibility with EN 60601 requirements. Avoid exposure to liquids, excessive heat, and mechanical stress; allow adequate ventilation around the adapter during operation.
