The THD-15 series is the latest generation of high performance 15W dc-dc converter
modules setting new standards concerning power density. This product comes in a
encapsulated package with dimensions of only 25.4 x 25.4 x 10mm and therefore
occupies 50%(!) less board space than existing 15W converters.
All models have wide 2:1 input voltage range and precisely regulated, isolated
output voltages. Built-in filters for both input and output minimizes the need for
external filtering. Further features include remote On/Off and short circuit protection. Typical applications for these converters are battery operated equipment,
instrumentation, distributed power architectures in communication and industrial
electronics and everywhere where space is limited on the PCB.
