The MINMAX MRZI100 series is a generation of high performance 100W DC-DC converters in a quarter brick package, designed specifically for railway applications with popular 36-160 VDC input ranges. MRZI100 is approved by railway industry standard EN 50155 and complies with EMC standard EN 50121-3-2. Advanced circuit topology provides a very high efficiency of up to 91.5%, which allows baseplate temperatures of up to 105℃ and very high I/O isolation up to 2000VAC. It also has reinforced insulation, which is designed to meet stringent requirements and harsh environments. Further product features include under-voltage, overload/voltage/temperature, short circuit protection, remote On/Off control (positive/negative logic), output voltage trim, and output sense. It also complies specifically fire protection test EN45545-2 to ensure safety during railway/railroad vehicle operation.
