The TEP-150WI Series is a family of high power density dc-dc converter modules
with ultra-wide 4:1 input voltage range which come in an ultra-compact metal
case with screw terminal connection. Suitable for a wide range of applications, the
TEP-150WI series was particularly designed with industrial applications in mind.
The modules have flanges for easy chassis or wall mounting. A very high efficiency allows an operating temperature up to +50°C with natural convection cooling.
Further features include adjustable output voltage with constant current characteristic for battery charger applications.
