The NFS110 medical series is a 80 to 110W universal input AC/DC power supply on a 7

x 4.25 inch card with a maximum component height of 1.8 inches for use in medical

applications. The NFS110 medical series has the same generic feature set as the

standard NFS110 series but have been designed with lower safety ground leakage and

higher isolation as required for medical safety approval. The NFS110 provides 80W of

output power with free air convection cooling which can be boosted to 110W with

20CFM of air. Standard features include overvoltage and short-circuit protection. The

series, with full medical safety approval to EN60601 and UL2601, meets conducted

emissions EN55022 level A. The NFS110 medical series is designed for use in low

power medical, dental and laboratory applications such as dialysis machines,

monitoring equipment, instrumentation and infusion pump controls.

Notes

1Convection cooled, 80W maximum.

2Peak outputs lasting less than 60 seconds with duty cycle less than 10%.

Total peak power must not exceed 110W.

3Forced air, 20CFM at 1 atmosphere, 110W maximum.

4Figure is peak-to-peak. Output ripple is measured across a 50MHz

bandwidth using a 12 inch twisted pair terminated with a 47µF 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 NFS110-7902P, for 24V output

stated regulation IA/ IB≤5. This output will maintain ±5.0% regulation if

IA≤5A, where IA= +5.1V output current and IB= +24V 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 90oC and no

semiconductor case temperature should exceed 100oC.

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

local Artesyn representative or use the on-line model number search tool at

Mechanical Notes

AMetallic or non-metallic stand-offs (maximum diameter 5.4mm) can be

used in all four mounting holes without affecting safety approval.

BThe ground pad of the mounting hole near J1 allows system grounding

through a metal stand-off to the system chassis.

CThe heatsink 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 heatsink 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. Two different kits

are available, order part number ‘NFS110 COVER KIT’ or ‘NFS110C’.
