NFS40 Medical

3 of 4

Embedded Power for

Business-Critical Continuity

Specifications Contd.

Notes

1

Natural convection cooling, 40 W maximum.

2

Forced air, 20 CFM at 1 atmosphere, 50 W maximum.

3

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.

4

50 MHz bandwidth, peak-to-peak, measured differentially.

5

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

initial tolerance, load currents within stated limits, and output voltages

regulation.

6

A minimum load of 0.5 A is required on the +5 V output to obtain full current

from the negative output.

7

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

positive or negative.

8

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.

9

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

making thermal measurements.

10 Although the minimum output current of the NFS40-79XXJ is 0 A, a 4 W

minimum load is required to achieve design MTBF.

11 Three orthogonal axes, sweep at 1 octave/min, 5 minute dwell at four major

resonances.

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.
