Traco Power now sells a new TEQ 40 Series of 40-W railway industrial dc/dc converter. This new offering has dual outputs capable of supplying ±12, ±15, and ±24 Vdc.

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 9.5 to 36, 18 to 75, and 43 to 160-V input ranges and outputs of 5, 12, 15, 24, ±12, ±15, and ±24 Vdc.

High efficiency of 87 to 88% and thermal-block construction allows a convection (full-load) operating temperature range of -40° C to +83° C — and up to +93º C with power derating. Features include:

• 2,250 Vdc I/O Isolation
• Under-voltage lockout
• Over temperature protection
• Short-circuit protection

These dc/dc converters satisfy 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.

Products are in stock and available through the TRACO POWER global distribution network with manufacturing lead times of 12-14 weeks. For more information (including specifications, drawings and safety documentation) visit www.tracopower.us/teq40.
