5. Filter appearance and elements
The very compact and neat design of ecosine evo passive harmonic filters is realized by a two-stage
construction. The filter construction of all frame size are identical, except the position of the load choke. The
load choke is build on the upper-stage of the filter for frame size A- F, and on the lower-stage of the filter for
frame sizes G – H, which are explained in detail in the following sections.
5.1 IP 00 version, frame size A - F
The general design of the ecosine evo passive harmonic filter IP 00 versions with fan module, aux. power
supply module, TDJ module and RC damper module (E0FAJRX) is shown in Figure 10.
