The 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. The approvals according to standards EN 50155 and EN 61373 qualify them for railway and transportation systems. Additional qualification for the fire behavior 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.
