In general, we do not recommend installing two power supplies directly side by side. Each unit should maintain a minimum clearance of 20 mm from adjacent devices to ensure proper heat dissipation and reliable operation.
When power supplies are installed too closely together, heat accumulation may occur, which can increase internal temperatures and require output power derating.
Power derating curves and thermal guidelines are provided in the technical datasheets for most models. These curves illustrate how output power must be adjusted under different ambient temperatures and installation conditions, including spacing and airflow.
We recommend referring to the product-specific datasheet for detailed information. If your application has space constraints or requires closer installation, please contact our technical support team for further evaluation.
