TRACO POWER has announced the release of their THN 15WIR family of ruggedised DC/DC converters designed for harsh environments in a miniature 1x1x0.40” footprint. The converters offer increased resistance against electromagnetic interference, shock/vibration and thermal shock with EN 50155 and EN 61373 compliance making them suitable for railway, transportation and harsh industrial environments.

The 15W THN 15WIR family consists of 27 models offering ultra-wide 4 to 1 Input ranges of 9-36/18-72/36-160VDC and output voltages of 3.3/5/12/15/24/±5/±12/±15VDC.

The ultra-wide input range satisfies a ±40% deviation of nominal required of today’s railway and transportation systems.

These models feature I/O isolation of 3,000VDC, efficiency of 88-91% (model dependent), a full load operating temperature range of -40°C to 75°C (up to 90°C with 50% load derating), input under-voltage-lockout, short circuit protection, remote On/Off and output voltage trim.

All models are qualified to railway EN50155, EN61373, EN 45545-2 standards and safety approved to IEC/EN 60950-1, UL60950-1 with a built-in EMI filter to meet EN55022 class A emissions.
