FEATURES

PRODUCT OVERVIEW

The MINMAX MTQZ50 series is a new generation of high performance, convection-cooled 50W 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 +85°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.
