Use in a tightly sealed enclosure
When the DC/DC Converter is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside. In such situations, the inside temperature defines the ambient temperature for the DC/DC Converter.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure. The DC/DC Converter is placed in the middle of the box, no other heat producing items are inside the box.
The temperature sensor inside the box is placed in the middle of the right side of the DC/DC Converter with a distance of 1cm.
