This rugged, railway quality DC-DC converter is designed for an operating life up to 30 years. By eliminating optocouplers in the feedback loop and significantly reducing the component count, the MTBF of the unit is improved over conventional designs. The use of the latest silicon carbide (SiC) semiconductor technology contributes to high conversion efficiency, high power density and a significantly smaller size than similar designs. Cooling is by conduction via baseplate. The internal board is conformal coated for immunity to humidity and contamination. The construction is robust and withstands high levels of shock and vibration. The input and output are filtered for low noise. Full electronic protection eliminates failure due to abnormal operating conditions, including application errors. Large design headroom and the use of components with established reliability also contribute to the long operating life of the unit. The converter meets the requirements of EN 50155 for electronic equipment used on railway rolling stock. It is manufactured at our plant under strict quality control.
