DC/DC Railway Converter TEP 150WI Series, 150 Watt Shielded metal case with screw terminals Ultra wide 4:1 input voltage ranges 936, 1875, 43160 VDC EN 50155 approval for railway applications Very high efficiency up to 89% Constant current output characteristic for battery load applications Optional with input filter to meet EN 55032 class B UL 62368-1 IEC 62368-1 Wide Operating temperature range: The modules have originally been designed for harsh industrial environment. 40C to +75C High EMC immunity against surge, burst, radiated and conducted disturbances and the shock/ vibration and thermal shock resistance make them very popular Under voltage lock-out, for stringent requirements. With the extended input voltage ranges that cover overtemperature & reverse input the nominal 24, 36, 72 and 110 VDC with 40 % tolerance and the approval protection in accordance to EN 50155 standard they now also offer a reliable solution for Easy chassis and wall mounting mobile and stationary railway applications. At 100% load the current character- istics goes from constant voltage to constant current what makes the units also 3-year product warranty suitable for battery charger applications. With protection against over-tempera- ture, overload, short-circuit, reverse input, overvoltage and input under-voltage lock-out they are hard to destroy.
