NFS80 Series

3 of 4

Embedded Power for

Business-Critical Continuity

Specifications Contd.

Notes

1

Natural convection cooling.

2

Peak output current lasting less than 60 seconds with duty cycle ≤10%. During

peak loading, outputs may exceed total regulation limits.

3

Forced air cooling, 20 CFM @ 1 atmosphere.

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, line voltage within stated limits, load currents within stated

limits, and output voltages adjusted to their factory settings. Also, for stated

6

Pins 10 and 11 are a floating output, which can be referenced as either positive

or negative. Pin 10 is positive with respect to pin 11. Either pin 10 or 11 must

be connected to return (pins 4-7) for proper operation.

7

Derating curve is application specific for ambient temperatures > 50 °C, for

optimum reliability, no part of the heatsink should exceed 110 ºC and no

semiconductor case temperature should exceed 115 ºC.

8

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

making thermal measurements.

9

Three orthogonal axes, random vibration, 10 minute test for each axis.

10 This product is only for inclusion by professional installers within other

equipment and must not be operated as a stand alone product.

11 For EMI compliance unit may need to be mounted on a metal chassis.

12 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.

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