Notes

1. Guaranteed by design, not tested.

2. Up to 70% of the total output power is available from either output

providing the opposite output is simultaneously carrying 30% of the

total power.

3. Effect on negative Vout from 50%/50% loads to 70%/30% or

30%/70% loads.

4. Effect on negative Vout from 50%/50% loads to +Pout=50%,

-Pout=10%.

5. Unit will shut down above approximately 45V but will be undamaged

and will restart when voltage drops into normal range.

6. Recovery time is measured from application of the transient to point at

which Vout is within 1% of final value.

7. Transition time > 10 μs.

8. Tested on release from inhibit.

9. Shall not compromise DC performance
