The TEN 20WIR series is a family of high performance 20 Watt dc/dc converter

modules featuring ultra wide 4:1 input voltage ranges in a 2” x 1” 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 standard

features include remote On/Off, over voltage protection, under voltage lockout

and short circuit protection. Low input current characteristics at minimal load make

these converters also the ideal solution for battery-operated systems. Typical ap-

plications are in wireless networks, telecom/datacom, industry control systems and

measurement equipments.
