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 tem-
perature up to +60°C 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.
