Sine Wave Output Filter Modules deliver a smoother sinusoidal waveform with minimal residual ripple, effectively addressing issues commonly associated with square waveforms featuring high voltage spikes, often observed at the output of motor drives. By integrating these filter modules, challenges encountered when utilizing motor drives in long cable applications are mitigated.
Additionally, they enable the use of low voltage motor drives with medium voltage motors by positioning them in front of step-up transformers.
