Test results and significant waveforms

Doc ID 16261 Rev 3

11/33

For user reference, waveforms of the input current and voltage at the nominal input voltage

mains and nominal load conditions are shown in

Figure 5 and 6.

The power factor (PF) and the total harmonic distortion (THD) have been measured too and

the results are shown in

Figure 7 and 8. As visible, the PF remains close to unity throughout

the input voltage mains and the total harmonic distortion is very low.
