Thermal Considerations
In order to ensure safe operation of the PSU in the end-use equipment, the temperature of the components listed in the table below must not be
exceeded. Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of any direct air flow). See
Mechanical Details for component locations.

Service Life
The estimated service life of the CCB200 is determined by the cooling arrangements and load conditions experienced in the end application. Due to
the uncertain nature of the end application this estimated service life is based on the actual measured temperature of a key capacitor within the product
when installed in the end application.
The graph below expresses the estimated lifetime for a given component temperature and assumes continuous operation at this temperature.
