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 dened 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 specic for ambient temperatures >50 °C, for

optimum reliability no part of the heatsink should exceed 110 oC and no

semiconductor case temperature should exceed 115 oC.

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’ sufx 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

search tool at http://www.Emerson.com/EmbeddedPower to nd a suitable

alternative.

Mechanical Notes

A In order to meet safety requirements, a non-metallic stand-off is mandatory for one hole as specied 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 signicantly attenuates common mode noise.

D A standard enclosure kit is available for mounting which contains all screws, connectors and necessary mounting

hardware. Order part number NFS40CJ.
