EPR-16 - LinkSwitch 2.75 W Charger/Adapter

9.6 Conducted EMI
All measurements were taken at the peak output power point with a line voltage of
230 VAC. This line voltage represents the worst case; results are lower at 115 VAC.
Limts shown are for EN55022B / CISPR22B
Final measurements were taken in all cases, representing the worst case of both phase
and indicated as either “X” on quasi peak results or “+” on average results.
Results with and without the optional components L2, R4 and C6 are shown to illustrate
the improvement in radiated EMI (50 MHz to 60 MHz region).
In all cases, a 10 dB or greater margin was obtained.
