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 efficien- cy allows an operating temperature up to +50°C with natural convection cooling. Further features include adjustable output voltage with constant current characteris- tic for battery charger applications.
The TEP 150WI Series from TracoPower offers high‑power‑density DC/DC converter modules in a compact, shielded metal case with screw‑terminal connections. Designed for industrial use, the series features an ultra‑wide 4:1 input voltage range, constant‑current output for battery‑charging applications, and over‑temperature protection.
The handbook lists detailed electrical specifications, including input and output voltage ranges, maximum output currents, efficiency up to 87 %, and protection features such as isolation voltage of 2250 VDC and short‑circuit recovery. Mechanical data such as dimensions, weight, and mounting recommendations are also provided.
