Thermal Considerations

If a converter, mounted on a PCB, is located in free, quasi-stationary air (convection cooling) at the indicated maximum ambient

temperature T

A max (see table Temperature specifications) and is operated at its nominal operating conditions, the case temperature

measured at the measuring point of case temperature T

C (see Mechanical Data) will approach the indicated value TC max after the

warm-up phase. However, the relationship between T

A and TC depends heavily on the conditions of operation and integration into

a system. The thermal conditions are influenced by input voltage, output current, airflow, temperature of surrounding components

and surfaces, and the properties of the printed circuit board. T

A max is therefore only an indicative value.

Caution: The case temperature T

C measured at the measuring point of case temperature TC (see Mechanical Data) shall under no circumstances

exceed the specified maximum value. The installer must ensure that under all operating conditions T

C remains within the limits stated in the

table Temperature specifications.

Overtemperature Protection

The converters are protected from possible overheating by an internal temperature monitoring circuit. It shuts down the converter

above the internal temperature limit, and automatically restarts, after the temperature dropped.
