15W DC-DCs for Railway and Industrial Systems
Traco Power has added the THN 15WIR series of ruggedized 15 Watt dc-dc converters designed to deliver the highest reliability in harsh environments. The converters have an increased resistance against electromagnetic interference, shock/vibration and thermal shock. The approvals according to standards EN 50155 and EN 61373 qualify them for railway and transportation systems.
With extra wide input voltage ranges of 9- to 36-Vdc, 18- to 75-Vdc and 36- to 160-Vdc, the nominal input voltages of 24-, 48-, 72-, 96- and 110-Vdc are covered while a ±40% deviation (transients) from nominal does not affect the function. With a 1†x 1†package and an efficiency of about 90% enables these dc-dc converters have an operating temperature range of -40 to 75 degrees C at full load or up to 90 degrees C with 50% load derating.
The qualification for the fire behavior of components according to EN 45545-2 and the safety approval according IEC/EN 60950-1, UL60950-1 support a potential compliance test of the application. Built-in EMI 55022 class A filter, input under-voltage-lockout, short circuit protection, remote On/Off and output voltage trim are further features which facilitate system design.
