NFN25 Datasheet, PDF (1/2 Pages) Artesyn Technologies – Dual and triple output 25 Watt AC/DC universal input switch mode power supplies

[ 2 YEAR WARRANTY ]
NFN25 SERIES
Dual and triple output
• 85VAC to 264VAC universal input range
• 120VDC to 370VDC input voltage range
• Fixed frequency operation
• Overvoltage protection (+5V output)
• Meets EN55022 limit B and FCC part 15 limit B line
conducted noise
• VDE, UL and CSA approved
The NFN25 Series of universal input, 25 Watt switching power supplies are
mechanically equivalent to the industry standard NFS40, but are optimised for
operation at lower output power levels. The NFN25 Series uses an advanced,
fixed frequency design which further reduces the line-conducted noise below
EN55022 and FCC limit B and specifies a much lower leakage current. The
supplies deliver 25W continuous, 35W peak and regulate to zero load. NFN25
Series power supplies are particularly suitable for telecoms applications such as
modems, PABX’s and networking systems.
