Thermal Considerations
If a converter is located in free, quasi-stationary air
(convection cooling) at the indicated maximum ambient
temperature T
and is operated at its nominal input voltage and output
power, the temperature measured at the Measuring point of
case temperature T
the indicated value T
However, the relationship between T
heavily on the conditions of operation and integration into a
system. The thermal conditions are influenced by input
voltage, output current, airflow and temperature of
surrounding components and surfaces. T
contrary to T
Notes: Sufficient forced cooling or an additional heat sink
allows T
exceeded.
For -2 units at an ambient temperature T
convection cooling, the maximum permissible current for
each output is approx. 50% of its nominal value as per
figure.
Output Response
The reaction of the outputs is similar whether the input
voltage is applied or the inhibit is switched low.
An output voltage overshoot will not occur when the
converter is turned on or off.
