Notes
1. Share operation not characterized for dual outputs.
2. Up to 80% of the total output power is available from either output
provided that the opposite output is simultaneously carrying 20% of the
total output power. one of the outputs must always provide a minimum
of 20% of the total output power to meet cross regulation. Negative Vout
cross regulation is referenced to 50%/50% balanced loads (at 100% of
total rated output power - full load).
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. Second output at 50%
7. Recovery time is measured from application of the transient to point at
which Vout is within 1% of final value.
