NCLOSURE
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 box, no other heat producing items are inside the
box. The load is placed outside 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
1cm.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
