Harmonic content at nominal mains voltage

One of the main benefits of the HVLED815PF device is the correction of input current

distortion, decreasing the harmonic contents below the limits of the relevant regulations.

Figure 13 and Figure 14 show the harmonic content at 100 Vac/50 Hz and 230 Vac/50 Hz

input voltage.

The measurement at 100 Vac, 50 Hz; PIN = 12.1 W; POUT = 10 W; PF = 0.994:

Figure 13. Harmonic content at 100 Vac/50 Hz

The measurement at 230 V, 50 Hz; PIN = 11.8 W; POUT = 9.9 W; PF = 0.963:

Figure 14. Harmonic content at 230 Vac/50 Hz

Figure 13 and Figure 14 show as the harmonics respect the limits for Class C equipment.
