Sine Wave Filter
Sine Wave Filter
Motor protection, VFD output filter, Long cable drive
Technical Data:
- Voltage withstand test: 3000VAC/50Hz/5mA/10s without flashover breakdown (capacitor release)
- Carrier frequency: 2-8KHz
- Pressure drop: 8% -12%
- No load current: ≤ 8%
- Voltage harmonic distortion distortion THDu ≤ 5%
Product Description
The ND series sine wave filter products are used to improve the voltage waveform at the output end of the frequency converter, correct the PWM waveform output by the frequency converter, convert it into a sine wave, extend the output distance of the frequency converter up to 3KM, effectively suppress high-frequency and DV/DT radio frequency interference, reduce output harmonic components, reduce eddy current losses and noise of the motor, extend the ser vice life of the motor, and improve system reliability.
