Conducted emissions test

Conducted emissions have been measured in neutral and line wires, using a peak detector

and considering the limits for lighting applications specified in EN55015. The measurements

have been performed at 110 and 230 Vac lines. The results are shown in Figure 11, 12, 13,

14

and 15.

Since the emission level is below both the quasi-peak and average limits with acceptable

margin, the power supply passes the pre-compliance test.
