RECOVERY
Notes
1. Share operation not characterized for dual outputs.
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%
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.
8. Recovery time is measured from application of the transient to point at
which Vout is within 1% of final value.
