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.

Electrical Characteristics: 25°C Tc, 270 VDC Vin, 100% load, free run, unless otherwise specified.
