Medical-grade 12 V 25 W adapter

The Mean Well GSM25B12-P1J delivers a regulated 12 V output at 2.08 A for a total of 25 W. It accepts a universal 100-240 V AC input at 50/60 Hz and terminates in a 5.5 x 2.0 mm barrel connector. A detachable power cord is included for immediate use. The unit carries medical-grade safety approvals and multiple protection circuits.

Ideal for medical and industrial equipment

This adapter suits devices that require a stable 12 V 2.08 A supply and a 5.5 x 2.0 mm plug, such as patient monitors, diagnostic instruments or industrial controllers. Buyers whose equipment demands a different voltage, a higher current rating or an alternative connector type should select another model. Overseas purchasers must source a local mains cord separately.

The 5.5 x 2.0 mm barrel connector decides fit

The centre-positive 5.5 x 2.0 mm barrel jack is the single specification that determines compatibility with the target device. Verify the equipment’s power socket matches this exact diameter and pin size before ordering. An incorrect connector will prevent connection even when voltage and current ratings align.
