PRODUCT OVERVIEW
The MINMAX MKZI10 series is a new range of high performance 10W isolated dc-dc converter within encapsulated 2"x1" package which specifically design
for railway applications. There are 12 models available for railway input voltage of either 24(9~36)VDC or 48(18~75)VDC or 72/110(40~160)VDC and tight
output voltage regulation. Further features include over current, over voltage, short circuit protection, remote ON/OFF, output trim and EMI filter meets
EN55022 & FCC Part15 Class A as well. MKZI10 series conform to vibration and thermal shock test meets EN61373, cooling, dry and damp heat test
meets IEC/EN 60068-2 and railway EMC standard EN50121-3-2 and complies also with railway standard EN50155 (IEC60571). MKZI10 series offer an
highly reliable solution for critical applications in railway systems, battery-powered equipment, measure instrumentation and many critical applications.
