Notes

Power Supply Efficiency affects the current draw in AC Watts from the
branch circuit. As efficiency increases, the current draw in AC Watts
decreases.
To calculate maximum theoretical current draw in AC Watts, multiply the
maximum power supply output in DC Watts by the reciprocal of the power
supply efficiency.
Theoretical values are typically higher than published values which are
based on measured outputs under controlled test conditions.
