Electrical Characteristics: -55°C to +125°C TC, 28 VDC VIN, 100% load, free run, unless otherwise specified.
notes:
1. Guaranteed by design, not tested.
2. Parallel load share function is not characterized for dual output models.
3. 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.
4. Effect on negative Vout from 50%/50% loads to 70%/30% or
30%/70% loads.
5. Effect on negative Vout from 50%/50% loads to 50% then 10% load on negative
Vout.
6. Unit will shut down above approximately 45V but will be undamaged and will
restart when voltage drops into normal range.
7. Transition time 100 s ±20%.
8. Recovery time is measured from application of the transient to point at which Vout
is within 1% of final value.
9. Tested on release from inhibit.
10. Shall not compromise DC performance.
