THN 30WIR Series

Traco Power has introduced a new THN 30WIR series of DC/DC converters which is shielded by a metal enclosure on all six sides for the lowest susceptibility to electromagnetic interference and is designed for the highest reliability in harsh environments. The THN 30WIR series can operate at ambient temperatures ranging from -40°C up to +65°C without derating and without the need for additional cooling. Moreover, with an output power of 30 Watts, this series expands the portfolio of EN 50155 railway certified wide input voltage range 1”x1" DC/DC converters.


This Series features power conversion efficiency of up to 91% and its full encapsulation guarantees the highest resistance to thermal shocks as well as mechanical shocks and vibration. The THN 30WIR is EN 61373 certified for mechanical shock and vibration and EN 45545-2 certified for fire behavior.
