Notes
1 Natural convection cooled, 40 W maximum.
2 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.
3 Forced air, 20 CFM at 1 atmosphere, 50 W maximum.
4 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.
5 Total regulation is dened 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.
6 A minimum load of 0.5 A is required on the +5 V output to obtain full current
from the negative output.
7 The NFS40 offers the possibility of power sharing between outputs. Consult
factory for details.
8 Derating curve is application specic 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.
9 A 4 W 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 NFS40-7628J has separately linear regulated +12 V and -12 V 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.
14 The ‘J’ sufx indicates that these parts are Pb-free (RoHS 6/6) compliant.
15 NOTICE: Some models do not support all options. Please contact your local
Emerson Network Power representative or use the on-line model number
