DC/DC Converters TEN 25WI Series, 25/30 Watt Features UL 60950-1 ◆ Ultra wide 4:1 input voltage range ◆ Adjustable output voltage ◆ Remote On/Off ◆ Continuous short circuit protection ◆ Over voltage protection ◆ Over temperature protection ◆ I/O isolation 1500 VDC ◆ Input filter meets EN 55032, class A and FCC, level A without external components ◆ Fully RoHS compliant ◆ 3-year product warranty 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.
