The PKE8411API from Flex Power Modules is an Isolated DC-DC Converter that converts an input voltage of 9 - 75 V to an output voltage of 5 V. It delivers an output power of up to 40 W and has an efficiency of 89%. This isolated converter can withstand an input-to-output isolation voltage of 2250 V and meets functional insulation and safety requirements as per the IEC/UL 62368. It also complies with the EN 45545-2 EMC safety standard, making it suitable for railway applications. 

This DC-DC converter also supports safety features such as input under voltage shutdown, remote control, output over-voltage protection, over-temperature protection, output short-circuit protection, and output voltage adjust functions, providing enhanced reliabiltiy. This RoHS-compliant DC-DC Converter is available in a PCB-mount package that measures 50.8 x 25.4 x 11.9 mm.
