Use in a Tightly Sealed
Enclosure
When the power supply is installed in a tightly sealed enclosure, the
temperature inside the enclosure is higher than outside. In such situations, the
inside temperature defines the ambient temperature for the power supply.
The following measurement results can be used as a reference to estimate the
temperature rise inside the enclosure.
The power supply 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 power supply with a distance of 1 cm (0.39 in.).
