The THD-12WI series is a range of high performance, isolated 12W dc/dc converter
modules featuring ultra wide 4:1 input voltage ranges in a DIP-24 package with
industry-standard footprint. Overload and overvoltage protection as well as remote
On/Off are included as standard. Built-in filters for both input and output minimizes
the need of external filtering. Full SMD-design with exclusive use of ceramic capaci-
tors guarantees a high reliability and long product lifetime. Typical applications for
these converters are industrial electronics, instrumentation, data communication sys-
tems and battery operated equipment with limited space available on the PCB.
