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.
