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 30%/70% or 70%/30%

loads.

4. Effect on negative Vout from 50%/50% loads to 10% then 50% load

on negative Vout.

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. Parallel/current share operation is not characterized for dual output

models.

Electrical Characteristics: –50°C to +100°C Tc, 28 VDC Vin, 100% load, free run, unless otherwise specified.
