NFC25 SERIES
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

The NFC25 series of dc-dc converters provide 25 Watts of power in a low
profile, 11 mm, 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. The input voltage ranges encompass 9 Vdc to18 Vdc,
18 Vdc to 36 Vdc and 36 Vdc to 72 Vdc. The NFC25 Series is ideal for
applications such as telecommunications, process control, factory automation,
mobile and test equipment.
