Thermal Consideration
Thermal Test Point
Sufficient airflow should be provided to ensure reliable operating of the module. Therefore, thermal
components are mounted on the top surface of the module to dissipate heat to the surrounding
environment by conduction, convection, and radiation. Proper airflow can be verified by measuring the
temperature at the middle of the baseplate.

Power Dissipation
The module power dissipation is calculated based on efficiency. The following formula reflects the
relationship between the consumed power (P
