NFN25 SERIES Dual and triple output [ 2 YEAR WARRANTY ] • 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.
