Notes
1. 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.
2. Effect on the negative output under the following conditions:
+P
30% to 70%; –P
70% to 30%
3. Effect on the negative output under the following conditions:
+P
out
50%; –P
out
10% to 50%
4. Unit will shut down above approximately 45V but will be undamaged and will
restart when voltage drops into normal range.
5. Indefinite short circuit protection not guaranteed above 125°C case.
6. Recovery time is measured from application of the transient to point at which
Vout is within 1% of final value.
7. Guaranteed but not tested.
Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, radiation level O, unless otherwise specified.
