MTQZ75-110S12: DC-DC Module, Vin :66-160 (VDC), Vout: 12 (VDC), Iout: 6250 (mA)

The MINMAX MTQZ75 series represents a groundbreaking 75-watt DC-DC converter designed for high-performance applications in railway settings. The series is designed in a quarter brick size according to international standards, featuring fully encapsulated potting assembly to resist external environmental interference. Two widely accepted input voltage ranges are offered: 72 (43-101)VDC and 110 (66-160)VDC, with a total of 8 selectable models providing precise output voltages of 5/12/15/24. All models comply with railway certification standards EN 50155 and EMC standards EN 50121-3-2. The MTQZ75 series employs advanced circuit topology, achieving up to 92% overall efficiency. It maintains stable electrical performance even in dynamically changing environments. With an optimized thermal design, the series supports a wide temperature range from -40°C to +85°C. For customers concerned about thermal performance, dedicated heat sink options are also provided. Other features include 3000VAC isolation withstand, reinforced insulation system, remote on/off control, output voltage trimming, and output voltage remote sensing, offering customers greater flexibility in design. To withstand harsh railway environmental conditions, the MTQZ75 series has undergone reliable testing according to standards such as EN 61373 for vibration and shock/bump, IEC/EN 60068-2-1, 2, 30 for cooling, dry & damp heat, and EN 45545-2 for fire protection. In addition to passing internationally recognized basic test conditions, MINMAX has subjected the series to even more stringent conditions, ensuring customers have a long-term reliable solution for railway applications. The trusted MTQZ75 series has been successfully applied in various cases, including railway signal indicator lights, door control systems, fire monitoring and alarm systems, automatic driving systems, and battery energy management systems for railways.
