The 350DNG40-12-8 from Bel Fuse is a Buck DC-DC Converter that converts an input voltage of 240-450 V to an output voltage of 10-15 V. It delivers an output power of up to 4 kW and has an efficiency of less than 93%. This converter is based on the 2nd generation conversion technology that produces DC voltage in hybrid and electric vehicles suitable to power low-voltage accessories. It can also be paralleled with up to 8 units to further enhance the output power. This buck converter offers full galvanic isolation between the input and output for better performance. It can be controlled using a CAN bus serial interface and also has UDS functionality with CAN FD/cybersecurity to ensure a highly reliable operation. 

This E-mark-certified converter consists of a comprehensive set of protection circuitries to ensure protection against over-current, over-temperature, over-voltage, and reverse polarity faults. It is also liquid-cooled to maintain thermal stability. This RoHS-compliant DC-DC converter is available in an IP67/IP6K9K-rated module that measures 264 x 55 x 355 mm and is ideal for construction, ground support, on/off-highway vehicles, marine equipment, and mining applications.
