Notes
1. guaranteed by design, not tested.
2. The sum of the two aux outputs is not to exceed 10 watts. The maximum
load per aux output is 9 watts.
3. To maintain regulation when operating the ±Aux at full load, a minimum
load of 300 mA is required on the main.
4. Measured on each output one at a time with the other outputs at full load.
5. Indefinite short circuit protection not guaranteed above 125°C (case).
6. Response of each output as all outputs are simultaneously transitioned.
Main: 50% - 100% - 50% of main full load
Auxiliaries: 25% - 50% - 25% each, of total auxiliary full load
7. Recovery time is measured from application of the transient to point at
which Vout is within 1% of regulation.
8. Tested on release from inhibit.
Electrical Characteristics: -55°C to +125°C TC, 28 VDC Vin, 100% load, free run, unless otherwise specified.
