The TEQ-40WIR Series is a family of isolated high performance railway 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 +92ºC with power derating. Further features include under voltage lockout, over temperature protection and short circuit protection. High power block with excellent thermal convection
