Notes
1. Share operation not characterized for dual outputs.
2. Up to 80% of the total output power (current) is available from either output
providing the opposite output is carrying 20% of the power (current) in use.
3. Assumes balanced loads on the outputs.
4. Effect on the negative output from 50%/50% loads to 70%/30% or 70%/30%
loads.
5. Unit will shut down above approximately 425V but will be undamaged
and will restart when voltage drops into normal range.
6. Indefinite short circuit protection not guaranteed above 125°C case.
7. Second output at 50%
8. Recovery time is measured from application of the transient to point at
which Vout is within 1% of final value.
