4. Modular Design: How to choose optional modules
Ecosine evo passive harmonic filters provide optimized solution for your application by merely plugging a new
module.
The base module of FN 3441, FN 3451, FN 3443 and FN 3453 series contains line choke, trap choke and
trap capacitor, which helps reduce THID to 5% for motor drives with an 8% DC-link choke present.

The base module of FN 3440, FN 3450, FN 3442 and FN 3452 series contains line choke, load choke, trap
choke and trap capacitor, which helps reduce THID to 5% for motor drives without DC-link choke present.
The base module schematic is shown in Figure 7.
