EMC Considerations
Thermal Considerations
The KW006/010 power module is designed to meet
EN55022 Class B Conducted emissions with a simple
filter, as shown in Figure 19. Test results are shown in
Figure 20. Further improvement to the emissions at the
fundamental can be achieved by increasing the value
of C3 and C4. Please contact your Lineage Power
sales representative, if you need further information.
The power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation.
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of
the module will result in an increase in reliability. The
thermal data presented in this data sheet is based on
physical measurements taken in a wind tunnel. The test
set-up is shown in Figure 21. Please refer to the
Application Note “Thermal Characterization Process
For Open-Frame Board-Mounted Power Modules” for a
detailed discussion of thermal aspects including
maximum device temperatures.
