Overtemperature Protection
Output Overvoltage Protection
A temperature sensor on the converter senses the average
temperature of the module. It protects the converter from
being damaged at high temperatures. When the
temperature exceeds the over temperature protection
threshold, the output will shut down. It will allow the
converter to turn on again when the temperature of the
sensed location falls by the value of Over temperature
Protection Hysteresis
When the voltage directly across the output pins exceeds
the output overvoltage protection threshold, the
converter will enter hiccup mode. When the fault
condition is removed, the converter will automatically
restart.
Reverse Protection
Reverse voltage protection circuits prevent damage to
power supplies and electronic circuits in the event of a
reverse voltage applied at the input terminals. The
protection ensures that the components are not damaged
by accidental swap of the power supply connections.
Thermal Consideration
Sufficient airflow should be provided to help ensure reliable
operating of the WGI20-48S05L.
Therefore, thermal components are mounted on the top
surface of the WGI20-48S05L to dissipate heat to the
surrounding environment by conduction, convection and
radiation. Proper airflow can be verified by measuring the
temperature at the middle of the base plate.
