Fastest active filter, now in its sixth generation…

MaxSine Compact is a highly versatile active harmonics filter. It can be programmed to cancel problematic harmonics, reduce flicker caused by highly dynamic loads, correct power factor and even balance network currents. 

How does it work? Put simply, it measures problematic harmonic currents and injects them back into the supply, but with a 180° phase shift. This cancels out the offending ones, thereby getting rid of the problem. It can be easily programmed to deal with specific harmonics up to the 50th order such as those associated with Variable Speed Drives, UPSs or office loads. 

No compromises have been made in the design or manufacture of MaxSine Compact. With thousands of units installed worldwide, it is a proven product. This, together with an improved project management approach to sales, ensures that every application is correctly engineered and commissioned.

Now in its sixth generation, the unit has evolved to incorporate processing speeds that enable an adjustable response time of up to 1 network period in the fast mode and even less than one millisecond in ultra-fast mode. This makes it the fastest active filter, ensuring both efficiency and accuracy automatically adjusting to changing load conditions. The implemented web-server is exceptionally easy to use, yet provides access to the widest range of information. Harmonic spectrum data, current and voltage waveforms, internal and external temperature as well as voltage, current and power measurement data are just some of the choices of information displayed.
