The TEN 8WI series is a family of high performance 8 Watt dc/dc converter
modules featuring ultra wide 4:1 input voltage ranges in a DIP-24 package with
industry- standard footprint. Input voltages up to 160 VDC, excellent EMC char-
acteristics and EN 50155 approval make this product the best choice for many
demanding applications in railroad and transportation systems. Further stan-
dard features include remote On/Off, over voltage protection, under voltage
lockout and short circuit protection. Typical applications for these converters
are also in wireless networks, telecom/datacom, industry control systems and
measurement equipment.
