The harmonic filters are to reduce the harmonic distortion in power side circuit of VFD. The filters are constructed by the reactor and capacitor units,and achieve very high reliability.

Features

The harmonic suppression filter is a passive filter designed to suppress harmonic currents in order to meet harmonic guideline measures. It primarily reduces the 5th and 7th harmonics and also reduces harmonics up to the 25th order.

Selection Method

When selecting the harmonic filter, ensure that the current does not exceed the motor’s full-load current (A). It is also possible to select based on the current values of general-purpose inverters.

Product Lineup

The harmonic filter lineup is extensive, with power supply voltages of 200V and 400V, and frequencies of 50Hz and 60Hz available. (A 50Hz/60Hz dual-use version can also be considered.) For dimensions, functions, and specifications, please refer to the respective documents.

Main Applications
