The TEN 12WI series is a family 12W DC/DC converter modules featuring ultra
wide 4:1 input voltage ranges in a compact 2“x1.0“ low profile package with in-
dustry-standard footprint.
A high efficiency up to 84% allows operating temperatures from –40°C to +85°C.
A built-in EMI input filter complies with EN 55022, class A without any external
components.
Further standard features include remote On/Off (optional), over voltage protec-
tion and continuous short-circuit protection.
Typical applications for these converters are battery operated equipment and distri-
buted power architectures in communication and industrial electronics, everywhere
where isolated, tightly regulated voltages are required.
