Dual-Output 20W DC-DCs with Convection-Cooled Thermal-Block Design

Traco Power has extended their TEQ 20 Series of 20-Watt dc-dc converters for railway and rugged industrial applications with dual outputs of ±12- and ±15-Vdc.

The TEQ 20WIR 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 18 models offering 9- to 36-Vdc, 18- to 75-Vdc and 43- to 160-Vdc input ranges and outputs of 5-, 12-, 15-, 24-, ±12-, and ±15-Vdc.

High efficiency of 87-88% combined with thermal-block construction allows a convection / full-load operating temperature range of -40°C to +83°C (up to +93°C with power derating). Features include: 2,250Vdc 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 a 3-year product warranty Traco Power’s 3-year warranty.
