Harmonic filters from KEB – high efficiency and grid quality
Harmonic filters from KEB are characterised by their high filter performance and long service life. They compensate harmonic currents and enable a sinusoidal current consumption. In addition, they improve the grid quality and reduce the THDi value (Total Harmonic Distortion) to below 8 % – for the protection of drives and the maximum energy efficiency of your systems.
What distinguishes harmonic filters from KEB:
- ✔ available as 400 V / 50 Hz and 480 V / 60 Hz solutions
- ✔ suitable for all consumers with B6 input
- ✔ high overload capacity up to 150 %
- ✔ compact, ready-to-connect design
- ✔ compliance with international norms and standards (e.g. EN 61000-3-4, EN 12015)
- ✔ multiple consumers simultaneously possible per unit
- ✔ longer service life of DC link capacitors
- ✔ reduced current load on the transformer

How does a harmonic filter work?
In modern drive systems, frequency inverters and rectifiers generate so-called harmonic currents or harmonics due to their switching frequencies. These burden the power supply and the neutral conductor and lead to grid feedback, distortions of the sinusoidal voltage and interference with other devices.
Harmonic filters – also referred to as harmonic wave filters – specifically counteract these effects. They compensate unwanted harmonic currents and restore a clean sinusoidal form of the grid voltage. This improves the grid quality and ensures reliable operation of all connected consumers.
In industrial applications, especially in machines with multiple frequency inverters, harmonic filters are indispensable. They
- minimise electromagnetic interference,
- protect sensitive controls,
- extend the service life of motors and grid components.
KEB relies on passive harmonic filters with innovative filter technologies, which ensure optimal compensation at different frequencies – even with dynamic load changes and high full load.
