Figure 124: Sine filter DX-SIN3…
The DX-SIN3… sine filter removes high-frequency components from the vari-
able frequency drive's output voltage (U
2
). This reduces the conducted and
radiated emission. The sine filter's output voltage has a sine wave shape
with a small superimposed ripple voltage.
The sinusoidal voltage's total harmonic distortion is typically 5 to 10%. This
reduces noise and losses in the motor.
