MTQZ75 SERIES
DC/DC CONVERTER 75W, Railway Applications
PRODUCT OVERVIEW
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 EN50155 and complies also with EMC standard EN50121-3-2.
Advanced circuit topology provides a very high efficiency up to 92% which allows operating temperatures range of -40°C to +70°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 and over-temperature protection.
