Module Derating
Experiment Setup
From the experimental set up shown in figure
33, the derating curves as figure 34 can be
drawn. Note that the PWB ( printed-wiring
board ) and the module must be mounted verti-
cally. The passage has a rectangular cross-
section. The clearance between the facing
PWB and the top of the module is kept 13 mm
(0.5 in.) constantly.
Convection W
Convection Without Heat Sinks
ithout Heat Sinks
Heat transfer can be enhanced by increasing
the airflow over the module. Figure 34 shows
the maximum power that can be dissipated by
the module.
In the test, natural convection airflow was mea-
sured at 0.05 m/s to 0.1 m/s (10 ft./min. to 20
ft./min.). The 0.5 m/s to 4.0 m/s (100 ft./min. to
800 ft./min.) curves are tested with externally
adjustable fans. The appropriate airflow for a
given operating condition can be determined
through figure 34.
Example 1. How to calculate the minimum
airflow required to maintain a desired Tc?
If a AV60A-048L-050D033(N) module operates
with a 48V line voltage, a 15 A of Io2, and a 40
° C maximum ambient temperature, What is the
minimum airflow necessary for the operating?
Determine PD ( referenced Fig.30 ) with con-
dition:
Vin = 48V, lO1 = 1.5A, lO2 = 15A
Get: PD = 15.5W
From: TA = 40 °C
