The NFS25 series is a 25W universal input AC/DC power supply on a 5 x 3 inch card
with a maximum component height of 1.2 inches for use in 1U applications. The NFS25
series is available with a wide range of models in the industry standard 5 x 3 inch
footprint and has proven itself to be reliable and versatile product for a wide range of
communication and industrial applications. The NFS25 provides 25W of output power
with free air convection cooling which can be boosted to 30W with 20CFM of air.
Standard features include OVP and short circuit protection. The series, with full
international safety approval and the CE mark, meets conducted emissions EN55022
level A. The NFS25 series is designed for use in low power data networking, computer,
telecom and industrial applications such as wireless switchers, hubs, POS terminals,
PABX’s and machine control. This list is not exclusive as the generic feature of the
series with industry standard output configurations provide a solution for most high
volume applications including many industrial applications.

Natural convection cooling.
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.
3 Figure is peak-to-peak. Output noise measurements are made across a
50MHz bandwidth using a 12 inch twisted pair, terminated with a 47µF
capacitor.
4 Total regulation is defined as the static output regulation at 25°C, including
initial tolerance, line voltage within stated limits, load currents within stated
limits and output voltages adjusted to their factory settings. Also, 0.5 ≤ IA /
IB ≤ 3 to maintain stated regulation. This does not apply to the NFS257628.
5 The NFS25-7628 has separately regulated +12V and -12V outputs. The
loading condition in note 4 does not apply.
6 Derate linearly from 25 Watts at 50oC to 12.5 Watts at 70oC.
7 Derating curve is application specific for ambient temperatures > 50°C, for
optimum reliability no part of the heatsink should exceed 120oC and no
semiconductor case temperature should exceed 125oC.
8 Caution: Allow a minimum of 1 second after disconnecting the power
before making thermal measurements.
9 A 4 Watt minimum load is required to achieve design MTBF.
10 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.

Mechanical Notes
A In order to meet safety requirements, a non-metallic stand-off is mandatory
for one hole as specified in the mechanical drawing above.
B The ground pad of the mounting hole near P1 allows system grounding
through a metal stand-off.

C 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 P1. Use metal stand-offs attached to a common metal
chassis. This connection also significantly attenuates common mode noise.
D A standard L-bracket and cover is available for mounting which contains all
screws, connectors and necessary mounting hardware. Order part number
‘NFS40 COVER KIT’.
