HPQ-12/25-D48 Series
Isolated 300-Watt Quarter Brick DC-DC Converters
Vertical Wind Tunnel
Murata Power Solutions employs a computer controlled
custom-designed closed loop vertical wind tunnel, infrared
video camera system, and test instrumentation for accurate
air?ow and heat dissipation analysis of power products.
The system includes a precision low ?ow-rate anemometer,
variable speed fan, power supply input and load controls,
temperature gauges, and adjustable heating element.
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 sol-
dered down to a 10? X10? host carrier board for realistic heat
absorption and spreading. Both longitudinal and transverse
air?ow studies are possible 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 ther-
mal 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.
