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 defined as the static output regulation at 25

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 specific for ambient temperatures >50

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’ suffix 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
