The MINMAX MRZI150 series is a new generation of high performance 150W DC-DC converters in a quarter brick package, designed specifically for railway applications with popular 36-160 VDC input ranges. MRZI150 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 90%, which allows baseplate temperature up to 105℃ and very high I/O isolation up to 2000VAC, with 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 with fire protection test EN45545-2 to ensure safety during railway/railroad vehicle operation.
