NFC25 SERIES Single and triple output • Typical efficiency 80% • Low profile 0.43 inches • Remote ON/OFF • BTR2511 conformance • UL, CSA and TÜV approvals • EN55022 conducted emissions level B • Industry standard footprint • Fixed operating frequency • Load sharing facility The NFC25 Series of DC/DC converters provide 25 Watts of power in a low profile, 11mm, industry standard package. Key design specifications are tight line and load regulation, 80% efficiency, load sharing facility, conducted emissions to EN55022 level B, and the BTR2511 requirements (hold-up time, reverse polarity protection etc.). These specifications have been enhanced by adding such standard features as remote on/off, short circuit protection and overvoltage protection. Both single and triple output versions are available and the input voltage ranges encompass 9-18VDC, 18-36VDC and 36-72VDC. The [ 2 YEAR WARRANTY ] NFC25 Series is ideal for applications such as telecommunications, process control, factory automation, mobile and test equipment.
