PRELIMINARY
22.7. USE IN A TIGHTLY SEALED ENCLOSURE
When the device 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 device.
In the following test setup, the device is placed in the middle of the enclosure; no other heat producing items are
inside the enclosure. The load is placed outside the enclosure.
The temperature sensor inside the enclosure is placed in the middle of the right side of the device with a distance of
1cm.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
