It is a converter designed for railway applications, industrial or telecommunications.

Is certified with the regulations for railway EN50155 and EN45545-2 in front of the fire.

Can operate up to 55C at full load and 70 ° C at 60% load or 70 ° C ambient temperature with ventilation by driving without losses. Also supports a temperature range of more demanding level rail Tx to 85ºC ambient temperature for 10 minutes with ventilation by driving on a metal surface.

This converter semi-encapsulation has been designed for the most demanding applications at the level of vibration, temperature, and humidity. Has a low profile of only 40mm and uses only components prepared for high temperatures as for example capacitors of 105ºC.

It has a low noise and ripple, and high efficiency and is protected against reverse polarity at the input. The inrush current is limited by a resistor in series with a MOSFET to reduce the peak starting current to reliably regardless of the ambient temperature.

Its output is protected against short-circuits and overloads by limiting output current, this allows you to start loads with a high inrush.
