Isolated DC/DC Converter Specification Model No.:WGI20-48S05L Overtemperature Protection Output Overvoltage Protection A temperature sensor on the converter senses the average When the voltage directly across the output pins exceeds temperature of the module. It protects the converter from the output overvoltage protection threshold, the being damaged at high temperatures. When the converter will enter hiccup mode.
