Choosing a replacement supply
Start with the LED module voltage and total load, then compare the mains input, terminal layout and mounting dimensions with the existing supply. The model name by itself is not enough to establish interchangeability.
The listing specifies ventilation cooling and three protection functions. Installation dimensions, operating temperature and protection thresholds are not provided here; confirm those details for your cabinet before purchase. Protection features should not be read as a guarantee of uninterrupted operation.
