Customer Air Cooling (option C, U and open frame):
The following method must be used for determining the safe operation of PSUs.
The components listed in the following table must not exceed the temperatures given. To determine the component
temperatures the heating tests must be conducted in accordance with the requirements of the safety standard in
question.
Test requirements include: PSU to be fitted in its end-use equipment and operated under the most adverse
conditions permitted in the end-use equipment handbook/specification and which will result in the highest
temperatures in the PSU. To determine the most adverse conditions consideration should be given to the end use
equipment maximum operating ambient, the PSU loading and input voltage, ventilation, end use equipment
orientation, the position of doors & covers, etc. Temperatures should be monitored using type K fine wire
thermocouples (secured with cyanoacrylate adhesive, or similar) placed on the hottest part of the component (out of
any direct airflow) and the equipment should be run until all temperatures have stabilised.
Minimum 0.5m/s airflow for customer air cooling.
