TRACO Power announces TEQ 300WIR family of isolated DC/DC converter modules

300 W DC/DC Converter for Railway/Transportation & Industrial Applications

TRACO Power has released the TEQ 300WIR family of isolated, high performance DC/DC converter modules featuring ultra-wide 4:1 input ranges with Railway (EN 50155) and Industrial (IEC/EN/UL 60950-1 & UL 508) safety approvals.

The TEQ 300WIR family consists of 8 standard models offering input ranges of 18~75 / 43~160 VDC and output voltages of 12 / 24 / 28 / 48 VDC. These 300 watt chassis mount DC/DC converters are fully potted in a sealed metal case that has been qualified for resistance against shock and vibration in industrial and railway environments per EN 61373 and MIL-STD-810F. Their high efficiency and heatsink design allow for convection-cooled operation of -40°C to 80°C (up to 55°C without derating). Status and control features include remote on/off, remote sense and active current share. These converters measure a mere 6.00 x 4.00 x 1.52”.  All models are safety approved to IEC/EN/UL 60950-1, EN 50155, UL 508, CB test report and bear the CE Mark with a warranty of 3 Years.
