The TEP 100WIR 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
industry standard half brick package.
A very high efficiency allows full power operation without forced air cooling at 60°C
This temperature can be increased to 70°C with optional mounted heatsink or up
to 85°C when mounted on an iron base plate. The very wide input voltage range
and reverse input voltage protection make these converters interesting solution for
battery operated systems. Typical applications are in telecom/datacom, industry
control and railway systems for on board power distribution.
These series is available in many optional designs on demand --> see options.
