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.
