CUS100ME Handbook
Variations and limitations of use:
1. Component temperatures, for customer air, Conduction, or convection cooled models, must be monitored
in the end use application as described in the " Cooling for Unit Temperature Table" below .
Cooling for unit
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
standard in question. Consideration should also be given to the requirements of other safety standards.
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.
