ment.
The IR camera monitors the thermal performance of the Unit Under
Test (UUT) under static steady-state conditions. A special optical port
is used which is transparent to infrared wavelengths.
Both through-hole and surface mount converters are soldered down
to a 10" x 10" host carrier board for realistic heat absorption and

spreading. Both longitudinal and transverse air?ow studies are pos-
sible by rotation of this carrier board since there are often signi?cant
differences in the heat dissipation in the two air?ow directions. The
combination of adjustable air?ow, adjustable ambient heat, and
adjustable Input/Output currents and voltages mean that a very wide
range of measurement conditions can be studied.
The collimator reduces the amount of turbulence adjacent to the UUT
by minimizing air?ow turbulence. Such turbulence in?uences the
effective heat transfer characteristics and gives false readings. Excess
turbulence removes more heat from some surfaces and less heat
from others, possibly causing uneven overheating.
Both sides of the UUT are studied since there are different thermal
gradients on each side. The adjustable heating element and fan, built-in
temperature gauges, and no-contact IR camera mean that power supplies
are tested in real-world conditions.
