The TEN 8WI series is a family of high performance 8 Watt dc/dc converter mo-
dules featuring ultra wide 4:1 input voltage ranges in a DIP-24 package with indus-
try-standard footprint. Input voltages up to 160 VDC, excellent EMC characteristics
and EN 50155 approval make this product the best choice for many demanding
applications in railroad and transportation systems. Further standard features inclu-
de 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 equipments.
