EMC
Class 2: Filtered Industrial
This level of performance will allow the manufacturer/assembler to self-certify their apparatus for
compliance with the EMC directive for the industrial environment as regards the EMC performance
characteristics of the power drive system. Performance limits are as specified in the Generic Industrial
Emissions and Immunity standards EN 50081-2 and EN 50082-2.
Emissions:
Radiated Emissions
Conducted Emissions
Immunity:
Supply Voltage Distortion
Voltage Fluctuations, Dips, Unbalance,
Frequency Variations
Magnetic Fields
Electrostatic Discharge
Burst Interference
Radio Frequency Electromagnetic Field,
amplitude modulated
Radio Frequency Electromagnetic Field,
pulse modulated
Class 3: Filtered - for residential, commercial and light industry
This level of performance will allow the manufacturer / assembler to self-certify compliance of their
apparatus with the EMC directive for the residential, commercial and light industrial environment as
regards the EMC performance characteristics of the power drive system. Performance limits are as
specified in the generic emission and immunity standards EN 50081-1 and EN 50082-1.
Emissions:
Radiated Emissions
Conducted Emissions
Immunity:
