TRACO POWER extends their TEQ 40 Series of 40 watt railway / rugged industrial DC/DC converters with dual outputs of ±12 / ±15 / ±24VDC. The TEQ 40WIR are a series of isolated high-performance railway DC/DC-converter modules with ultra-wide 4:1 input voltage ranges. The series is comprised of 21 models offering 9-36 / 18-75 / 43-160 V input ranges and outputs of 5 / 12 / 15 / 24 / ±12 / ±15 / ±24VDC. 

High efficiency of 87 to 88% combined with thermal-block construction allows a convection / full-load operating temperature range of -40°C to +83°C (up to +93ºC with power derating). Features include: 2,250 VDC I/O Isolation; under voltage lockout; over temperature protection; and short circuit protection.

Series is qualified for EN 61373 / MIL-STD-810 for mechanical shock, thermal shock and vibration. Models are safety approved to UL/IEC/EN 60950-1 (CB Report) and EN50155 with an internal filter for EN 55032 class B conducted and radiated emissions, supported by TRACO POWER's three-year warranty.
