The Traco Electronic THN 10UIR, TEN 30UIR and TEN 40UIR are railway approved series of high-performance DC/DC converters with ultra-wide 12:1 input voltage range and output power of 10, 30 and 40 Watts respectively. The compact, fully encapsulated converters provide an increased resistance against shock/vibration, and thermal shock. A high efficiency of up to 90% give the converters an effective temperature range of –40°C up to +70°C (with heatsink up to 80°C) without derating. Thanks to the dedicated holdup capacitor connection, they meet extended holdup-time requirements without the need for bulky input capacitors.
Qualification for fire behaviour according to EN 45545-2
The approvals according to standards EN 50155 and EN 61373 qualify them for railway and transportation systems. Additional qualification for the fire behaviour of components according to EN 45545-2 and the safety approval according to IEC/EN/UL 62368-1 support a potential compliance test of the application. All models offer an I/O-isolation voltage of 3’000 VDC and feature an active under voltage lockout function, remote on/off and adjustable outputs to ensure that these converters fit in any ruggedized applications.
