Appendix A: AC Current Draw Calculations
A.1 DAA2 Current Draw Calculations
Maximum AC current draw varies by DAA2 model. Refer to the appropriate table worksheet in
Section A.1.2 for the maximum AC draw figure. Follow the procedures in Section A.1.1 to
calculate AC draw.
A.1.1 Worksheet Procedures
1. Two columns must be filled out and totaled for each amplifier. Enter the “Basic Draw”
figure into the appropriate columns (either A and B, or C and D).
2. In those same two columns, enter the figures for the application draws that apply.
3. Sum both columns, and enter the totals in the “AC Draw Totals” row. The figure in the
column with the highest total must be equal to or less than the maximum AC current draw
indicated.

The highest total of column A
and column B must be <
the
maximum AC current draw
allowed of 4.68A.
The highest total of column C
and column D must be <
the
maximum AC current draw
allowed of 2.68A.
* A DAA2-5025 used as a backup will draw the same power as a primary when it is active.
** When the amplifier is active, the column A charger entry must be 0.79 or the column C entry must be 0.58, no matter what size the charger is.
