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.
