The MKZI20 series is a range of high performance 20W isolated DC-DC converters within an encapsulated 2″X1″package, which has been specifically design for railway applications. There are 18 models available for the railway system of multi-input voltage ranges including 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, output voltage trim, and conducted EMI EN 55032/11 Class A.

The MKZI20 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 also with Railway Certification EN 50155 (IEC 60571). The MKZI20 series offer a highly reliable solution for critical applications in railway systems, battery-
powered equipment, and measure instrumentation.
