DC/DC Converters TEP 75WI Series, 75 Watt Features Rugged, compact metal case Screw terminal adaptor available UL 60950-1 for easy connection Optional DIN-rail mounting kit Ultra wide 4:1 input voltage range u Full load operation up to 60C with convection cooling Undervoltage lockout Reverse input voltage protection Input protection filter (Models pictured with chassis mount adaptor / optional heatsink) 3-year product warranty The TEP-75WI 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, sealed 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. Four threaded M3 inserts in the module makes chassis mount or attachment of a heatsink for optimal thermal management very simple. For easy connection there is also an unique adaptor available with screw terminals. A very high efficiency allows an operating temperature up to +60C with natural convection cooling without power derating. Further features include output voltage trimming, Remote On/Off and under voltage lockout. The very wide input voltage range and reverse input voltage protection make these converters also an interesting solution for battery operated systems.
