How to use

Connect the adapter to the AC mains using a compatible IEC320-C13 power cord and plug the 48 V DC output into the device requiring power, observing correct polarity. Ensure the input voltage falls within the 85–264 V AC range before switching on. Place the adapter on a flat, stable surface or mount it near the powered equipment with adequate ventilation and free from obstructing objects.

Recommendations

To ensure reliable operation, allow at least 5–10 cm of clearance around the adapter for ventilation, avoid exposure to moisture and excessive dust, and verify that connected equipment does not exceed the 220 W output rating. Use a properly rated IEC power cord and follow local electrical safety regulations when installing.
