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.
  4. Power Supplies 7070758 and 7074835 were updated to 7074836. (GSAP 6221)
  5. Power Supply 7074836 is updated to 7305956. (GSAP TBD)
