Notes
1. Up to 90% of full power is available from either output providing the total power does not exceed 30 watts.
2. The effect on the output voltage of either output (held at 3 watts) when the other output is varied from 3 to 27 watts.
3. A low output impedance power source is required on the input to realize this start-up time. If less than full surge
current is available, start-up time will be longer
