Overview: DC/DC Railway Converter TEQ 40WIR Series, 40 Watt • High power block with excellent thermal
convection • Operating temperature -40°C to +92°C • Ultra wide 4:1 input voltage range • EN 50155 approval for railway
applications • Excellent efficiency up to 91% • Input filter meet EN 55032, class B • I/O isolation up to 2121 VAC • Under voltage lock-out circuit • Protection against overvoltage,
overtemperature and short circuit UL 62368-1 IEC 62368-1 • Output LED indicator The TEQ 40WIR Series is a family of isolated high performance DC/DC converter modules with ultra-wide 4:1 input voltage ranges which come in a rugged metal case. These converters are suitable for a wide range of applications, but the product is designed particularly also for industrial applications where often no PCB mounting is possible but the module has to be mounted on a chassis. A very high efficiency and the heatsink construction allows an operating temperature up to +83°C with natural convection cooling without power derating and up to +92°C with power derating.
