LOW TO MEDIUM POWER AC/DC POWER SUPPLIES
Natural convection cooling.
Peak output current lasting less than 60 seconds with duty cycle less than
5%. During peak loading, outputs may go outside of total regulation limits.
Total peak power output is 35 Watts.
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.
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, 0.5 ≤ I
I
7628.
The NFS25-7628 has separately regulated +12V and -12V outputs. The
loading condition in note 4 does not apply.
Derate linearly from 25 Watts at 50
Derating curve is application specific for ambient temperatures > 50°C, for
optimum reliability no part of the heatsink should exceed 120
semiconductor case temperature should exceed 125
Caution: Allow a minimum of 1 second after disconnecting the power
before making thermal measurements.
A 4 Watt minimum load is required to achieve design MTBF.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
