4.4 Low Harmonic Variants
The majority of the Beijer BFI-H3 product range is based on a low harmonic solution using
film capacitor technology to achieve compliance with EN 61000-3-12 without the need for
any additional equipment. This standard specifies limits for harmonic currents for equipment
connected to public low-voltage systems with input current > 16A and <= 75A per phase. It is
important to understand which models from the product range are of the low harmonic
technology.
In short, this means that the low harmonic drives do not require an input choke and should not
have one installed.
Drives outside of the above rated input current, are of standard electrolytic capacitor design
and could benefit from the use of input chokes if further harmonic reduction is required.
