Notes

1

Free air convection cooling.

2

20CFM forced air.

3

Peak output current lasting less than 60 seconds with duty cycle less

than 5%. During peak loading, output voltage may exceed total

regulation limits.

4

Figure is peak-to-peak for convection power rating. Output noise

measurements are made across a 20MHz bandwidth using a 6 inch

twisted pair, terminated with a 10µF electrolytic capacitor and a 0.1µF

ceramic capacitor.

5

Three orthogonal axes, random vibration 10 minutes for each axes, 2.4G

rms 5Hz to 500Hz.

For optimum reliability, no part of the heatsink should exceed 120˚C, and

no semiconductor case temperature should exceed 130˚C.

CAUTION: Allow a minimum of 1 second after disconnecting line power

when making thermal measurements.

standard EN55022 set-up with a stand alone NLP70-9693 unit placed on

a grounded metal plate with a line choke on the AC input and ground

wires (i.e. the wires are looped through an EMI suppression toroid).

For system compliance it is usually necessary to install an ‘off-the-shelf’

AC inlet with an integral line filter in the system chassis or to install a line

choke on the input wires as close as possible to AC entry point of the

system chassis. Please contact the applications group at Artesyn for

assistance with EMI compliance.
