The MINMAX MKZI10 series is a range of high performance 10W isolated DC-DC converter within an encapsulated 2″x1″ package, which is specifically design for railway applications. There are 18 models available for the railway system in multi-input voltage ranges from 24(9~36)VDC, 48(18~75)VDC, 72/110(40~160) VDC, and fixed output voltage regulation. Further features include under-voltage, overload, over voltage, short circuit protection, remote ON/OFF, and output voltage trim, as well as being EMI EN 55032/11 Class A approved as well. The MKZI10 series conform to vibration and thermal shock/bump test EN 61373, cooling, dry and damp heat test IEC/EN 60068-2-1,2,30, and railway EMC standard EN 50121-3-2. It also complies with Railway Certification EN 50155 (IEC 60571). The MKZI10 series offer a highly reliable solution for critical applications in railway systems, battery-powered equipment, measure instrumentation, and many critical applications.
