The THI 3 series is a new range of high isolation DC/DC converters with
a reinforced insulation system. The I/O- isolation voltage is specified for
4000VACrms. The circuit is encapsulated in a DIP-24 package.
There are 15 models available for 5, 12 and 24VDC input voltage and single
or dual output voltage. The THI-3 DC/DC converters offer a cost effective
solution for applications in industrial controls and medical instrumentation
requiring a certified supplementary or reinforced insulation system
to comply with industrial or latest medical safety standards.
