Power factor at nominal load
The “Power Factor” (PF) at the nominal load remains above 0.9 for every input mains
voltage.

Total harmonic distortion (THD) at nominal load
Figure 14 shows the total harmonic distortion versus line voltage:
Figure 14. Total harmonic distortion vs. AC line voltage at nominal load
The THD curve presents two minimum valley point corresponding to the Japanese and
European nominal voltage.
