Feature Descriptions
Output Overvoltage Protection
The output overvoltage protection consists of circuitry
that monitors V
exceeds the overvoltage threshold, then the module
will shutdown and attempt to restart.
Thermal Considerations
Heat is removed by convection and radiation to the
surrounding environment, sufficient cooling should be
provided to ensure reliable operation of the unit.
Considerations include ambient temperature, airflow,
module power dissipation, and need for increased
reliability.
The thermal reference point, T
tions is shown in Figure 24

Overtemperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the overtemperature threshold is exceeded
it will then wait for the unit to cool before attempting
to restart.
EMC Considerations
Figure 26. Suggested Configuration for EN55022
For assistance with designing for EMC compliance,
please refer to the FLTR100V10 data sheet
(FDS01-043EPS).
Layout Considerations
Copper paths must not be routed beneath the power
module mounting inserts. For additional layout
guide-lines, refer to FLTR100V10 data sheet
(FDS01-043EPS).
