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.

Convection cooled, 80W maximum.
Peak outputs lasting less than 60 seconds with duty cycle less than 10%.
Total peak power must not exceed 110W.
Forced air, 20CFM at 1 atmosphere, 110W maximum.
Figure is peak-to-peak. Output ripple is measured across a 50MHz
bandwidth using a 12 inch twisted pair terminated with a 47µF capacitor.
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 NFS110-7902P, for 24V output
stated regulation I
A
/ I
B
≤ 5. This output will maintain
±
5.0% regulation if
I
A
≤ 5A, where I
A
= +5.1V output current and I
B
= +24V output current.
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).
Power fail detect not available on single output models.
Derating curve is application specific for ambient temperatures > 50°C, for
optimum reliability no part of the heatsink should exceed 90
o
C and no
semiconductor case temperature should exceed 100
o
C.
Caution: Allow a minimum of 1 second after disconnecting the power when
making thermal measurements.
The user should read the PSU installation instructions in conjunction with
the relevant national safety regulations in order to ensure compliance.
Three orthogonal axes, random vibration, 10 minute test for each axis.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.

Mechanical Notes
A
Metallic or non-metallic stand-offs (maximum diameter 5.4mm) can be
used in all four mounting holes without affecting safety approval.
B
The ground pad of the mounting hole near J1 allows system grounding
through a metal stand-off to the system chassis.
C
The heatsink is grounded, and allows system grounding by mechanical
connection to the system chassis.
D
The supply must be mechanically supported using the PCB mounting holes
and may be additionally supported by the heatsink mounting holes.
E
It 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.
F
A 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’.
