Ambient temperature

The ambient temperature is described in DIN EN 60204-1. It describes the temperature in the electronics that guarantees optimum operation of electronic components or systems. If the ambient temperature is not maintained, components and systems may become less efficient and the service life of the products may be reduced. In addition, if the ambient temperature for electronic devices is not maintained, there is a risk of destruction, i.e. complete failure of the respective components or machine.

The rated ambient temperature is the highest temperature at which the transformer can be operated continuously under the intended operating conditions. Unless otherwise agreed, the transformers are designed for a maximum ambient temperature of 40°C.

The transformers must be installed in such a way that the necessary cooling is ensured. This is particularly important in enclosures with a high degree of protection. Transformers with cooling channels must be installed in such a way that the channels run vertically. Deviating from an ambient temperature of 40°C, the rated power must be reduced for higher temperatures in accordance with the following table.
