High Performance Output Filter – IP00 Series
IM00168
Performance
The following benefits can be realised with the
High Performance Output Filter
when connected between the ZENER
8000 inverter and a motor:
Significant reduction of RF voltages and currents achieving 40dB to 45dB attenuation.
Complies with AS61800.3 (Adjustable speed electrical power drive systems, Part 3: EMC requirements and
specific test methods) category C3 limits, category C2 limits and category
C1 limits (0.2 to 30MHz) (see below for definitions) in a typical installation with 100m of either unscreened or
screened motor cable.
Ideal solution for eliminating AM radio frequency interference
Maximum reduction of potential RF voltages and currents achieving 45dB to 50dB attenuation with screened
motor cable.
High efficiency, greater than 99%
Eliminate the need for installing screened motor cables.
The permissible cable length
1
between filter and motor is 500m.
Categories as defined in AS61800.3 are:
C1 limits apply to equipment in a domestic environment that does not require installation and commissioning
by a professional.
C2 limits apply to equipment in a domestic environment that does require installation and commissioning by
a professional.
•
C3 limits apply to equipment in a non-domestic environment.
•
C4 limits apply to equipment with currents above 400A and special cases.
Maximum rate of change of voltage (dv/dt) = 150V/μs
Maximum peak motor voltage with 100m of cable typically 120% of bus voltage

Cable resistive voltage drop should be taken into consideration when long cable runs are used.
