Notes
1. Guaranteed by design, not tested.
2. up to 70% of the total output power (current) is available from either output
provided the opposite output is carrying 30% of the power (current) in use.
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.
Electrical Characteristics: –55°C to +125°C Tc, 28 VDC Vin, 100% load, free run, unless otherwise specified.
