Notes
1Natural convection cooled, 40W maximum.
2Peak 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.
3Forced air, 20 CFM at 1 atmosphere, 50W maximum.
4Figure is peak-to-peak. Output noise is measured across a 50MHz
bandwidth using a 12 inch twisted pair, terminated with a 47µF capacitor.
5Total 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 the
NFS40-7628 power supply as it has regulated auxiliary outputs.
6A minimum load of 0.5A is required on the +5V output to obtain full current
from the negative output.
7The NFS40 offers the possibility of power sharing between outputs.
Consult factory for details.
8Derating 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.
9A 4W minimum load is recommended to achieve the design MTBF.
10 Caution: Allow a minimum of 1 second after disconnecting the power when
making thermal measurements.
11 Three orthogonal axes, sweep at 1 octave/minute, 5 minute dwell at four
major resonances.
12 The NFS40-7628 has separately linear regulated +12V and -12V outputs.
The loading conditions in Notes 5 and 6 do not apply.
13 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.

Mechanical Notes
AIn order to meet safety requirements, a non-metallic stand-off is mandatory
for one hole as specified in the mechanical drawing.
BThe ground pad of the mounting hole near P1 allows system grounding
through a metal stand-off.
CTo 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.
DA standard L-bracket and cover is available for mounting which contains all
screws, connectors and necessary mounting hardware. Order part number
‘NFS40 COVER KIT’.
