Natural convection cooled, 40 W 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 60 W.
Forced air, 20 CFM at 1 atmosphere, 50 W maximum.
Figure is peak-to-peak. Output noise is measured across a 50 MHz bandwidth
using a 12 inch twisted pair, terminated with a 47 µF 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 the NFS40-7628J
power supply as it has regulated auxiliary outputs.
A minimum load of 0.5 A is required on the +5 V 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 110
o
C and no
semiconductor case temperature should exceed 115
o
C.
A 4 W minimum load is recommended to achieve the design MTBF.
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 NFS40-7628J has separately linear regulated +12 V and -12 V outputs. The
loading conditions in Notes 5 and 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.
The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.
NOTICE: Some models do not support all options. Please contact your local
Emerson Network Power representative or use the on-line model number

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’.
