The NFS40 and NFN40 are industry standard 40 Watt power supplies with the
capability to supply 50W in a forced air ambient and to automatically operate
from any voltage between 85VAC and 264VAC. Use of MOSFET based
switching circuits allows for enhanced features such as output regulation down
to zero load (NFN40). Universal input voltage eliminates the need to change
jumpers or switch settings to cater for different or widely varying line voltages.
In addition to the input voltage range, VDE, UL, CSA, EN60950 and IEC950
approvals make the NFS40 and NFN40 ideal for use in equipment installed
throughout the world. The fixed frequency operation of the NFN40 further
reduces emissions below VDE class B and significantly reduces leakage current.
These low profile switchers with high power density are intended for use in
small, digital systems.

Natural convection cooled, 40W maximum.
Peak output current lasting less than 30 seconds with duty cycle less than
10%. During peak loading, outputs may go outside of total regulation
limits. Peak total power must not exceed 60W.
Forced air, 20 CFM at 1 atmosphere, 50W maximum.
Figure is peak-to-peak. Output noise is measured across a 50MHz
bandwidth using a 12 inch twisted pair, terminated with a 47µF capacitor.
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,
0.25<I(A)/I(B)<5.0 to maintain stated regulation. This does not apply to
NFS40-7628 and NFN40-7628 power supplies as both have regulated
auxiliary outputs.
A minimum load of 0.5A is required on the +5V output to obtain full current
from the negative output.
The NFS40 offers the possibility of power sharing between outputs.
Consult factory for details.

Derating curve is application specific for ambient temperatures >50°C, for
optimum reliability no part of the heatsink should exceed 110oC and no
semiconductor case temperature should exceed 115oC.
A 4W minimum load is required to achieve the NFS design MTBF. This
restriction does not apply to the NFN series.
Caution: Allow a minimum of 1 second after disconnecting the power when
making thermal measurements.
Three orthogonal axes, sweep at 1 octave/minute, 5 minute dwell at four
major resonances.
The NFS40-7628 and NFN40-7628 have separately linear regulated +12V
and -12V outputs. The loading conditions in note 5 and note 6 do not
apply.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.

Safety Ground
A NFS40 models only: In order to meet safety requirements, a non-metallic
stand-off is mandatory for one hole as specified in the mechanical
drawing.
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 (P1 for NFS40 models and J3 on NFN40 models).
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. Details are on
page 72. Order part number ‘NFS40 COVER KIT’.
