5. Temperatur differential

Variations in temperature (e.g. day-night, summer-winter, climate zones) have to be taken into account. Please enter the maximum temperature differential or determine the temperature differential in the enclosure based on the maximum allowable interior temperature (Ti) and the maximum expected ambient temperature (Tu):

Temperature differential K
6.Continuous stray power

The stray power (= self-warming) of all installed electrical load (e.g. transformers, relays, semiconductors, bus bars etc.) has to be taken into account if components are operated continuously.
