Delta A249 / A249A / A249B
1100 / 1200 Watt Power Supply

AC Input

DC Output

Efficiency of 300-2235

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. The 300-2138 was replaced by 300-2235 in T5220, T5240, and X4450
   in August 2010.
