3.6 Load Regulation

The data from the 390 VDC input efficiency measurements was used to generate the 12VSB and S12V regulation plot shown in Figure 3-27. No additional loading was applied to P18V and S12V.

The second plot (Figure 3-10) shows the voltage measured on P18V for different loading combinations on all outputs.
