The TEN 3WI series is a family of dc-dc converter modules with 3W output power,
featuring ultra wide 4:1 input voltage ranges of 9-36VDC or 18-75VDC. They come
in a DIP-24 plastic package with industry-standard footprint. A high efficiency up to
84% allows operation ambient temperatures of –40°C to +70°C at full load.
A built-in EMI input filter complies with EN 55022,class A without need of external
components. Further standard features include over voltage protection and conti-
nuous short circuit protection. Typical applications for these converters are battery
operated equipment and distributed power architectures in communication, instru-
mentation and industrial electronics, everywhere where isolated, tightly regulated
voltages are required
