Embedded Power for
Business-Critical Continuity
Notes
1Convection cooled, 80 W maximum.
2Peak outputs lasting less than 60 seconds with duty cycle less than 10%. Total
peak power must not exceed 110 W.
3Forced air, 20 CFM at 1 atmosphere, 110 W maximum.
4Figure 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.
5Total 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
regulation IA/ IB² 5. This output will maintain ±5.0% regulation if
IA² 5 A, where IA= +5.1 V output current and IB= +24 V output current.
6Single 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).
7Power fail detect not available on single output models.
8Derating 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.
9Caution: 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

Mechanical Notes
AMetallic or non-metallic stand-offs (maximum diameter 5.4mm) can be used in
all four mounting holes without effecting safety approval.
BThe ground pad of the mounting hole near J1, allows system grounding
through a metal stand-off to the system chassis.
CThe heat sink is grounded, and allows system grounding by mechanical
connection to the system chassis.
DThe supply must be mechanically supported using the PCB mounting holes and
may be additionally supported by the heatsink mounting holes.
EIt is always advisable to attach the power supply heat sink to another thermal
dissipator (such as a chassis or finned heatsink etc). The resulting decrease in
heat sink mounted component temperatures will improve power supply
lifetime.
FA standard L-bracket and cover is available for mounting which contains all
screws, connectors and necessary mounting hardware. The kit is available,
order part number “NFS110CJ” .
