ADNB 40W Series

EMI Emissions
The ADNB 40W series has been designed to comply with the Class B limits of EMI requirements of EN55022 (FCC Part
15) and CISPR 22 (EN55022) for emissions and relevant sections of EN61000 (IEC 61000) for immunity.
The unit is enclosed inside a metal box, tested at full load using resistive load.
Conducted Emissions
The applicable standard for conducted emissions is EN55022 (FCC Part 15). Conducted noise can appear as both
differential mode and common mode noise currents. Differential mode noise is measured between the two input lines, with
the major components occurring at the supply fundamental switching frequency and its harmonics. Common mode noise,
a contributor to both radiated emissions and input conducted emissions, is measured between the input lines and system
ground and can be broadband in nature.
