VLT® Advanced Active Filters

The VLT Advanced Active Filter is factory optimized for the most common applications. The unit is self tuning and can not be overloaded. If correctly sized, the filter reduces the current harmonic distortion of a system to less then 5%. Individual application optimizations are possible through two different compensation modes and priority settings.

Benefits

•Small compact housing

•Easy to use in retrofit applications

•One filter module can be used for several frequency converters

•The smallest filter available today in this power range

•Easy maintenance as all parts are accessible from the front. This means that the filter can be mounted side-by-side, saving even more space

•Easy cable access and bottom entry

•Standards conformant coated PCB’s

•100% factory test •Auto current sensor adaptation

Range 190-400A (380-480V)

The unit meets IP21/Nema 1 protection requirements as standard. IP54/Nema12 is available on request.

The unit comes as standard with a graphical Local Control Panel, supporting 28 languages. Display option of up to 5 lines can show unit performance, grid and load conditions.

LCP offers build-in help functions and fault logging in case of unit trips.

Two different RFI filters are available. The unit is equipped with an RFI class A2 filter as standard, but A1 filters are available also.

The AAF can be delivered with mains disconnect, fuses and/or RFI options, -all build-in to reduce occupied wall space.

Intelligent heat management The VLT Advanced Active Filter is built with back channel cooling, which transfers 85% of all heat through an IP54 segregated cooling duct. This reduces contamination of the electronic circuit and prolongs the product life.
