The MINMAX MTQZ75 series is a generation of high performance, convection-cooled 75W DC-DC converters designed specifically for railway applications.
Both 72(43-101)VDC and 110(66-160)VDC input voltage range is popular in railway usage, and also available in Minmax product lines.
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℃ to +80℃. 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.
