LV Sinus Filters
Sinus Filters are designed to convert the PWM output of variable frequency drives into a sinusoidal waveform, reducing stress on motors and eliminating high-frequency noise. They are ideal for long cable applications and environments where EMI reduction is critical.
Why Sinus Filters Matter
Sinus Filters enhance motor performance by converting PWM signals to smooth sinusoidal waves, reducing stress on motors, minimizing EMI emissions, and supporting reliable operation in sensitive installations.
Key Advantages
- Motor protection from PWM voltage stress
- Reduction of common-mode noise
- Extended motor cable lengths
- Minimized EMI emissions
- Improved drive system reliability
