RECOM RHF-R Feedback and Regenerative Harmonic Filter
In an ideal situation, all loads and sources have a pure sine current waveform. Unfortunately, the true waveforms of most devices are very different.
Product details
feedbackRHF-R harmonic filter with regeneration unit
Passive harmonic suppression of regenerative current
saidRevcon Corporation®harmonic filterRHF-RA / RBReduced harmonic distortion of current generated by regeneration modules such as RLD, RHD, or RFE.
saidRevcon RHF-RA/RBIt is a passive filter.It does not tune to various frequencies like an absorption circuit, but works like a band stop filter, which can significantly reduce all low order harmonics up to the 50th order.

For comparison, the following table shows the circuit feedback of the inverter and regeneration unit evaluated by THiD (total harmonic distortion of line current) at the nominal point of the inverter/rectifier:

If the system almost exclusively uses regeneration units or operates in a public energy supply network, using RHF-RA/RB can sustainably reduce the harmonic load of low-voltage systems in the long term.Passive Harmonic FilterREVCON RHF-RA / RBRepresents an effective, inexpensive, and highly efficient (?>98.5%) measure to reduce harmonic distortion.Only related to option EST.
