Notes

1

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

3%. During peak loading, outputs may go outside of total regulation limits.

Total peak power may not exceed 450W.

2

Forced air, 30 CFM at 1 atmosphere or 350LFM.

3

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

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

capacitor.

4

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.

5

Floating output can be adjusted from 4.5V to 16.5V and referenced as

either positive or negative.

6

Floating output can be adjusted from 15V to 30V and referenced as either

positive or negative.

7

Output shorts will cause all outputs to fold back, protecting the supply

from damage. An overvoltage or overtemperature condition will trip the

output crowbar, shorting the outputs and also cause foldback.

When the fault condition is cleared, the supply will automatically recover.

This supply can be configured to latch off in the event of any output short.

Disconnecting line power for 15 seconds will reset the latch. See

mechanical note B.

8

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

9

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

when making thermal measurements.
