Safety
The NFS40-79XXJ models are
approved to UL2601, CSA22.2 No.
125 and IEC601/VDE0750
standards. The NFS40-79XXJ
series is for use in ordinary,
patient-connect applications
under the UL2601 and CSA C22.2
No. 125 standards, and is
authorised for use in non-critical,
non-patient-connect applications
under the IEC601 standards.
The NFS40 medical series is a 40 W universal input ac-dc power
supply on a 5 x 3 inch card with a maximum component height of
1.2 inches for use in medical applications. The NFS40 medical
series has the same generic feature set as the standard NFS40
series but has been designed with lower safety ground leakage
and higher isolation as required for medical safety approval. The
NFS40 provides 40 W of output power with free air convection
cooling which can be boosted to 50 W with 20 CFM of air.
Standard features include overvoltage and short-circuit
protection. The series, with full medical safety approval to
EN60601 and UL2601 and the CE mark, meets conducted
emissions EN55022 level A. The NFS40 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.

Natural convection cooling, 40 W maximum.
Forced air, 20 CFM at 1 atmosphere, 50 W maximum.
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.
50 MHz bandwidth, peak-to-peak, measured differentially.
Total regulation is defined as the static output regulation at 25 ¡C, including
initial tolerance, load currents within stated limits, and output voltages
adjusted to their factory settings. Also, 0.25 ² IA / IB ² 5.0 to maintain stated
regulation.
A minimum load of 0.5 A is required on the +5 V output to obtain full current
from the negative output.
Single output models have floating outputs which may be referenced as either
positive or negative.
Derating curve is application specific for ambient temperatures >50 ¼C, for
optimum reliability no part of the heatsink should exceed 120 ¼C and no
semiconductor case temperature should exceed 130 ¼C.
Caution: Allow a minimum of 1 second after disconnecting the power when
making thermal measurements.
Although the minimum output current of the NFS40-79XXJ is 0 A, a 4 W
minimum load is required to achieve design MTBF.
Three orthogonal axes, sweep at 1 octave/min, 5 minute dwell at four major
resonances.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
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.
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
A In order to meet safety requirements, a non-metallic stand-off is mandatory for one hole as specified 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 significantly attenuates common mode noise.
D A standard L-bracket and cover is available for mounting which contains all screws, connectors and necessary mounting
hardware. Order part number ‘NFS40 COVER KIT’.
