20W DC/DC Converters Carry EN 50155 & IEC/EN/UL 60950-1 Approvals

TRACO POWER’s TEQ 20WIR family of isolated, high performance DC/DC converter modules offer ultra-wide 4:1 input ranges covering 9- to 160-Vdc input requirements, an extended ambient operating temperature range from -40°C to +93°C, and I/O isolation of 3 kVdc. Available in rugged metal cases, the converters are designed for railway and transit markets. They are also suitable for a wide range of industrial applications where no PCB mounting is possible and the module must be mounted on a chassis.


The TEQ 20WIR family consists of 12 standard models offering input ranges of 9.5~36 / 18~75 / 43~160 Vdc and output voltages of 5/12/15/24 Vdc. Features include: High efficiency operation up to 88%; EN55022 Class B EMI; I/O isolation of 3,000 VDC; under voltage lockout; protection against overvoltage/overtemperature and short circuit; and meet EN 61373 & MIL-STD-810F for mechanical shock & vibration and MIL-STD-810F for thermal shock. These converters measure 4.06 n. ix 2.25 in. x 1.03 in. All models are safety approved to IEC/EN/UL 60950-1 (Industrial / ITE Applications), and are qualified to EN 50155 for Railway immunity and bear the CE Mark. For more details and specs, a datasheet is available.
