| 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.

Peak output current lasting less than 60 seconds with duty cycle less than 5%. During peak loading, outputs may go outside of total regulation limits. Total peak power output is 35 Watts. Figure is peak-to-peak. Output noise measurements are made across a 50MHz bandwidth using a 12" twisted pair, terminated with a 47F cap. Total regulation is defined as the static output regulation at 25C, including initial tolerance, line voltage within stated limits, load currents within stated limits and output voltages adjusted to their factory settings. Also, 0.5I(A)/I(B)3 to maintain stated regulation. This does not apply to the NFN25-7628. The NFN25-7628 has separately regulated +12V and -12V outputs. The loading condition in note 4 does not apply. Derate linearly from 25 Watts at 50oC to 12.5 Watts at 70oC. Derating curve is application specific for ambient temperatures > 50C, for optimum reliability no part of the heatsink should exceed 120oC and no semiconductor case temperature should exceed 125oC. Caution: Allow a minimum of 1 second after disconnecting the power before making thermal measurements.

B To improve conducted noise, the ground pad of the mounting hole near the output connector should be connected with the ground pad of the mounting hole near J3. Use metal stand-offs attached to a common metal chassis. This connection also significantly attenuates common mode noise.
