TRACO ELECTRONIC Provides THN 15WIR Series of Ruggedized 15W DC/DC Converters

traco

The THN 15WIR series is a family of ruggedized 15W DC/DC converters for 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 9-36VDC, 18-75VDC and 36-160VDC, the nominal input voltages of 24, 48, 72, 96 and 110VDC are covered while a ±40% deviation (transients) from nominal does not affect the function. With a 1" x 1" package and an I/O isolation of 3,000VDC they are very compact.

The efficiency of about 90% enables an operating temperature range of -40°C to 75°C at full load or up to 90°C with 50% load derating. The qualification for the fire behaviour 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 the design in.
