Component Temperatures
Evaluating the VCCS300 product in the end application
To ensure the product is operating within its ratings in the end application the following procedure should be performed during the design stage.
1.
Setup the application in worst case conditions, considering mains voltage, output power, ambient temperature, mounting orientation, airflow, and cooling
restrictions.
2.
Install thermocouples in the positions listed below using glue to hold the thermocouples in place.
3.
Power the system and monitor the temperatures until they reach steady state.
4.
Ensure that all temperatures remain below recommended temperatures under normal conditions and do not exceed maximum temperatures under worst
case conditions. It is good practice to leave some margin in the design.
