Quarter-Brick Converters Hit The Rails

MINMAX's next generation quarter-brick dc/dc converter modules, the MTQZ50 and the MTQZ75, conform to railway emission standard EN 50121-3-2, as well as railway safety standards EN50155 and IEC 60571. In addition, the new DC-DC converters also adhere to vibration and shock standards specified by EN 61373, environmental standards IEC/EN 60068-2-1,2,30, and fire protection standards EN45545-2.

 

The MTQZ50 and MTQZ75 DC-DC converter series, consisting of eight models, integrate an I/O isolation of 3000VAC, offering ultra-wide input voltage ranges of 72 (43-101 VDC) and 110 (66-160VDC) with outputs of 5V, 12V, 15V, and 24V. The next generation DC-DC converters, providing an efficiency level of up to 92%, feature remote on/off control, remote sense, output voltage trim, overload/over-voltage/temperature protection circuits, and convection cooled ambient temperatures.
