Notes

  1. Power Supply Efficiency affects the current draw in AC Watts from the branch circuit. As efficiency increases, the current draw in AC Watts decreases.
  2. 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.
  3. Theoretical values are typically higher than published values which are based on measured outputs under controlled test conditions.
