Example 2. How to calculate the maximum
output power of a module in a certain con-
vection and a max. TA?
What is the maximum power output for a
AV60A-048L-050D033(N) operating at follow-
ing conditions:
Vin = 48V
v = 2.0 m/s (400 ft./min.)
TA = 40 °C
Determine PD ( Fig.34 )
PD = 16 W
Determine IO (Fig. 29 ):
IO = 14.5 A
Calculate PO:
PO = (VO) x (IO) = 5 x 14.5 = 72.5 W
Although the two examples above use 100 ° C
as the maximum case temperature, for
extremely high reliability applications, one may
design to a lower case temperature as shown in
Example 4 on page 22.
Heat Sink Configuration
Several standard heat sinks are available for
the AV60A dual output modules as shown in
Figure 35 to Figure 37.
The heat sinks mount to the top surface of the
module with screws torqued to 0.56 N-m (5 in.-
lb). A thermally conductive dry pad or thermal
grease is placed between the case and the
heat sink to minimize contact resistance (typi-
cally 0.1° C/W to 0.3° C/W) and temperature dif-
ferential.
Nomenclature for heat sink configurations is as
follows:
WDxyyy40
where:
x = fin orientation: longitudinal (L) or trans
verse (T)
yyy = heat sink height (in 100ths of inch)
For example, WDT5040 is a heat sink that is
transverse mounted (see Figure 25) for a 61
mm x 57.9 mm (2.4 in.x 2.28 in.) module with a
heat sink height of 0.5 in.
Heatsink Mounting Advice
A crucial part of the thermal design strategy is
the thermal interface between the baseplate of
the module and the heatsink. Inadequate mea-
sures taken here will quickly negate any other
attempts to control the baseplate temperature.
For example, using a conventional dry insulator
can result in a case-heatsink thermal imped-
ance of >0.5° C/W, while use one of the rec-
ommended interface methods (silicon grease
or
thermal pads available from ASTEC) can
result in a case-heatsink thermal impedance
around 0.1°C/W.
