Thermal Considerations
If an AC-DC converter is located in free, quasi-stationary air
(convection cooling) at the indicated maximum ambient
temperature
TA max (see table: Temperature specifications)
and is operated at its nominal input voltage and output
power, the temperature measured at the
Measuring point of
case temperature TC (see: Mechanical Data) will approach
the indicated value
TC max after the warm-up phase. How-
ever, the relationship between
TA and TC depends heavily
on the conditions of operation and integration into a sys-
tem. The thermal conditions are influenced by input volt-
age, output current, airflow, temperature of surrounding
components and surfaces.
TA max is therefore, contrary to
TC max, an indicative value only.
The relation between the maximum allowed output power
Po allowed and the temperature
TA of the surrounding air is
given in fig.:
Maximum allowed output power vs. ambient
temperature. The rates apply if the AC-DC converter is lo-
cated in free, quasi-stationary air (convection cooling).
Note: Sufficient forced cooling allows
TA to be higher than
the value given in the table if
TC max according to the table is
not exceeded.

Caution: The installer must ensure that under all operat-
ing conditions
TC remains within the limits stated in the
