DC/DC Converters
TEN 25WI Series, 25/30 Watt
The TEN 25WI series is a family of high performance dc-dc converter modules up to
30 Watt featuring ultra wide 4:1 input voltage ranges in a compact low profile case
with industry standard footprint. Standard features include remote On/Off, output
voltage trimming, over voltage protection, under voltage lockout, over temperature
and short circuit protection.
An other features is the internal EMI-filter to meet EN 55032, class A. Typical ap-
plications for these converter modules are industrial electronics, communication sys-
tems, battery operated equipment and distributed power systems.
