9 Thermal Performance
High temperature testing was completed in a sealed adapter enclosure at elevated
ambient of 45 °C under conditions of natural convection. Input voltage was set to
90/265 VAC with 47 Hz line frequency. The output was adjusted to maintain full load
1.93 W and 2.1 W, respectively.
All temperatures are regarded as well within normally acceptable operating temperature
ranges.
An infrared thermograph was taken of the unit operating open frame at room ambient.
This confirms that the correct components were selected for temperature measurement
in the table above and that high line is worst case for U1.
