Notes

1

Natural convection cooling (40W maximum).

2

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

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

3

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

4

Figure is peak-to-peak. Output noise measurements are made across a

50MHz bandwidth using a 12 inch twisted pair, terminated with a 47µF

capacitor.

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. For multiple

output units to maintain stated regulation then:

0.25

≤ I

0.50

≤ I

Minimum load must also be 4W to achieve design MTBF.

This does not apply to the NAL40-7628 which has a separately regulated

output, see note 8.

6

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

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

semiconductor case temperature should exceed 130°C.

7

Caution: allow a minimum of 1 second after disconnecting line power when

making thermal measurements.

8

The NAL40-7628 has separately linear regulated +12V and -12V outputs.

The loading conditions in note 5 do not apply.

9

This product is only for inclusion by professional installers within other

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