How to use

Mount the UHP-350-48 in a suitable enclosure or on a mounting surface with adequate ventilation. Connect the AC input to a mains supply within the specified 90–264 V range, observing proper wiring and earthing practices. Connect the 48 V DC output to the load, ensuring the load current does not exceed 7.3 A and that polarity is correct. Allow for appropriate cooling and do not block airflow around the unit during operation.

Recommendations

For reliable long-term operation, avoid operating at maximum rated ambient temperature and consider a margin below the 7.3 A output rating for continuous loads. Use proper fusing and transient protection on the input and output lines, and follow MEAN WELL installation guidelines from the datasheet for grounding and mounting.
