12 Conducted EMI

EMI was tested at room temperature, at 115 VAC & 230 VAC input, with a resistor load

on each output as follows; 3.3V / 1.6 ohms; 5V / 7 ohms; 12V / 31 ohms; -5V / 240 ohms;

-22V / 11K ohms; 33V / 16K ohms; VFD / 20 ohms. All plots are shown with output

common connected to the ground of the LISN, to show worst case results.
