DC/DC Converters
TEP 150WI Series, 150 Watt
The modules have originally been designed for harsh industrial environment. High
EMC immunity against surge, burst, radiated and conducted disturbances and the
shock/ vibration and thermal shock resistance make them very popular for stringent
requirements. With the extended input voltage ranges that cover the nominal 24,
36, 72 and 110 VDC with ±40 % tolerance and the approval in accordance to
EN50155 standard they now also offer a reliable solution for mobile and stationary
railway applications. At 100% load the current characteristics goes from constant
voltage to constant current what makes the units also suitable for battery charger
applications. With protection against over-temperature, overload, short-circuit, re-
verse input, overvoltage and input under-voltage lock-out they are hard to destroy.
