Railway & Harsh Industrial 12:1 DC/DC Converters

TRACO Power Railway and Harsh Industrial Ultra-Wide 12:1 DC/DC Converters, covering 9V_DC to 75V_DC or 14V_DC to 160V_DC input ranges, are suitable for harsh environments and are available in 10 power levels in five packages ranging from 10W to 200W. The ultra-wide input design allows the converter to act as an all-in-one solution if different input voltage ranges need to be covered in the same application, solving the issue of using multiple converters or having multiple solutions with different DC input ranges. The UIR products from TRACO Power offer reliable performance under the harshest environmental conditions. Additional features include high efficiency of up to 91%, a -40°C to +85°C ambient operating temperature range, and an I/O isolation voltage of 3000V_AC. These DC/DC converters are designed for railway and challenging industrial applications requiring a robust solution.
