Notes

1. Applies to both outputs.

2. Maximum combined output power is 12 watts. A maximum of 90% is available from either output.

3. 20% to 80% load on the positive output and 80% to 20% on the negative output. See Figure 8.

4. 50% load on the positive output and 50% to 20% load on the negative output. 50% load on the negative output and

50% to 20% load on the positive output. See Figure 7.

5. Indefinite short circuit protection not guaranteed above 85°C case temperature.

Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, unless otherwise specified.
