NFS110 Series

3 of 5

Embedded Power for

Business-Critical Continuity

Notes

1

Convection cooled, 80 W maximum.

2

Peak outputs lasting less than 60 seconds with duty cycle less than 10%. Total

peak power must not exceed 110 W.

3

Forced air, 20 CFM at 1 atmosphere, 110 W maximum.

4

Figure is peak-to-peak. Output ripple is measured across a 50 MHz bandwidth

using a 12 inch twisted pair terminated with a 47 μF capacitor.

5

Total regulation is defined at the static output regulation at 25 °C, including

initial tolerance, line voltage within stated limits and output voltages adjusted

to their factory settings. Also for NFS110-7902PJ, for 24 V output stated

6

Single output models have floating outputs which may be referenced as either

positive or negative. Higher voltage supplies, may be adjusted over a wide

output voltage range, as long as the total output power does not exceed 80

Watts (natural convection) or 110 Watts (forced air).

7

Power fail detect not available on single output models.

8

Derating curve is application specific for ambient temperatures > 50 °C, for

optimum reliability no part of the heatsink should exceed 90 °C and no

semiconductor case temperature should exceed 100 °C.

9

Caution: Allow a minimum of 1 second after disconnecting the power when

making thermal measurements.

10 The user should read the PSU installation instructions in conjunction with the

relevant national safety regulations in order to ensure compliance.

11 Three orthogonal axes, random vibration, 10 minute test for each axis.

12 This product is only for inclusion by professional installers within other

equipment and must not be operated as a stand alone product.

13 The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant. TSE

RoHS 5/6 (non Pb-free) compliant versions may be available on special request,

please contact your local sales representative for details.

14 NOTICE: Some models do not support all options. Please contact your local

Emerson Network Power representative or use the on-line model number
