DC/DC Converters
TEN 25 Series, 25/30 Watt
The TEN 25 series is a range of isolated DC/DC converters with high power density
in a 51x41x9.5mm shielded metal case. All 18 models have a wide 2:1 input volt-
age range. The very high efficiency allows a safe operating temperature range of
40C to +85C. Other features are internal EMI-filter to meet EN55022, class A
and remote On/Off. Typical applications for these converter modules are industrial
electronics, communication systems, battery operated equipment and distributed
power systems.
