MINMAX's MKZI10(P) series is a high-performance 10W isolated DC-DC converter designed specifically for railway applications. The MKZI10(P) series adopts the international standard 2"x1" package, offering a choice of 18 models suitable for various input voltage ranges such as 24(9-36)VDC, 48(18-75)VDC, 72/110(40-160)VDC, and achieves highly accurate output voltage. With an excellent circuit topology design, the MKZI10(P) series achieves an impressive conversion efficiency of up to 89%. The outstanding overall thermal design allows the MKZI10(P) series to operate in a working environment temperature range from -40℃ to +90℃, spanning a temperature difference of 130℃, making it highly suitable for extremely cold and hot harsh environments.
The MKZI10(P) series features multiple functions, including undervoltage, overcurrent, overvoltage, short circuit protection, remote on/off, output voltage trim, 3000VAC I/O isolation voltage, reinforced insulation system, and complies with conducted EMI EN 55032/11 Class A certification. In addition, the MKZI10(P) series has passed vibration and shock/bump tests EN 61373, cooling, dry, and damp heat tests IEC/EN 60068-2-1,2,30, and complies with railway EMC standard EN 50121-3-2, also obtaining railway certification EN 50155(IEC 60571). Through rigorous certification and testing processes, we are confident that the MKZI10(P) series can meet the stringent requirements of railway equipment to withstand harsh environmental conditions.
In addition, if customers prioritize the durability of materials and the severe temperature variations that devices may encounter, MINMAX also offers the MKZI10P series to meet these requirements. All models in this series have undergone Temperature Cycling Testing (TCT), demonstrating their ability to withstand 500 cycles of high and low-temperature variations (-40°C to +125°C) at a rate of 20°C/min. Furthermore, they have successfully passed the Temperature Humidity Bias Test (THB), enduring conditions of high temperature and humidity (85°C temperature & 85% humidity) for up to 1,000 hours.
With long-term reliability assurance, excellent electrical performance, and good thermal performance, the MKZI10(P) series has been widely applied by customers in various railway equipment, such as traction inverters, passenger information systems, safety monitoring systems, turnout monitoring systems, and more, providing the best solution for railway applications facing harsh conditions.
