Notes

1

Convection cooled, maximum 50W output power.

2

Peak outputs lasting less than 30 seconds with duty factor less than 10%.

During peak loading output may go outside total regulation limits.

Maximum output during peak loading is 60 Watts.

3

Forced air, 20 CFM at 1 atmosphere.

4

Figure is peak-to-peak. Output noise measurements are across a 50MHz

bandwidth made using a 12” twisted pair, terminated with a 47µF

capacitor.

5Total regulation is defined as the static output regulation at 25°C, including

initial tolerance, line voltage within stated limits and output voltages

adjusted to their factory settings. Also, for stated I(2) regulation: I(1)/I(2)≤5.

6A minimum load of 0.5 Amps is required on the +5.1V output to obtain full

current from the -12V output.

7

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

8

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

when making thermal measurements.

9

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

10 A 5 Watt minimum load is recommended to achieve design MTBF.

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

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