DC/DC Converter TEN 8WI Series, 8 Watt Ultra wide 4:1 input range up to 160 VDC Certified for Railway applications (EN 50155) Operating temperature range -40C to + 85C Input under voltage lockout UL 62368-1 IEC 62368-1 I/O isolation 1500 VDC 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 Input filter to meet EN 55022 class A 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 Remote On/Off 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.
