DC/DC Converter TEQ 40WIR Series, 40 Watt High power block with excellent thermal convection Operating temperature -40C to +92C Ultra wide 4:1 input voltage range EN 50155 approval for railway applications Excellent efficiency up to 91% Input filter meet EN 55022, class B I/O isolation up to 2121 VAC Under voltage lock-out circuit Protection against overvoltage, overtemperature and short circuit UL 508 UL 62368-1 IEC 62368-1 Output LED indicator The TEQ 40WIR Series is a family of isolated high performance DC/DC convert- er 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 tem- perature up to +83C with natural convection cooling without power derating and up to +92C with power derating. Further features include under voltage lockout, over temperature protection and short circuit protection. Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
