APPLICATIONS
The WRA-ZD-8W ＆ WRB-ZD-8W 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 characteristics 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. Typical applications for these
converters are also in wireless networks, telecom/datacom,
industry control systems and measurement equipments.
