The TEN 25 series is a new range of isolated DC/DC converters with
high power density in a 50x40x9.3mm shielded metal case. All 18 mod-
els have a wide 2:1 input voltage range. The very high efficiency allows
a safe operating temperature range of -40C to +71C. Other features
are internal EMI-filter to meet EN55022, classA and Remote ON/OFF.
Typical applications for these converter modules are industrial electron-
ics, communication systems, battery operated equipment and distributed
power systems.
