MTQZ75 Series Railway Certified DC-DC Converter 75W

The MINMAX MTQZ75 series is a new generation of high performance, convection-cooled 75W DC-DC converters designed specifically for railway applications. They are available for the popular railway input voltages of either 72(43-101)VDC or 110(66-160)VDC.  The converters conform to railway industry transient standard EN 50155 and complies also with EMC standard EN 50121-3-2.  Advanced circuit topology provides a very high efficiency up to 92% which allows operating temperatures range of -40°C to +80°C. For improved heat dissipation the modules can be supplied with a heatsink. Further product features include high, reinforced insulation, remote On/Off control, under-voltage shutdown as well as overload, over voltage, over temperature and short circuit protection.
