Sine Wave Filter(SFR)
Driven by the PWM inverter, the sine filter still provides sine wave output voltage when the switching frequency range is within the range of 2-8kHz. In the applications of inverter drives, such a filter can eliminate the problem of motor insulation failure and decrease electromagnetic interference by eliminating the high dV/dT related to inverter output waveform, so as to extend the life and improve the performance of the motor, and extend the output length of the inverter to up to 3KM. For the protection of wires and cables, the sine filter can avoid over-voltage of the drive motor with a long lead. In the application of other energy resources, wind generator, for example, the invertor restores the power to the utility power system through a step-up transformer. And such filters allow the use of a standard transformer. If the maximum value of the 
harmonic voltage distortion input to the transformer at full load and 60Hz is 5%, the harmonic voltage distortion input to the motor at full load is generally 5%

   Product Introduction

Driven by the PWM inverter, the sine filter still provides sine wave output voltage when the switching frequency range is within the range of 2-8kHz. In the applications of inverter drives, such a filter can eliminate the problem of motor insulation failure and decrease electromagnetic interference by eliminating the high dV/dT related to inverter output waveform, so as to extend the life and improve the performance of the motor, and extend the output length of the inverter to up to 3KM. For the protection of wires and cables, the sine filter can avoid over-voltage of the drive motor with a long lead. In the application of other energy resources, wind generator, for example, the invertor restores the power to the utility power system through a step-up transformer. And such filters allow the use of a standard transformer. If the maximum value of the harmonic voltage distortion input to the transformer at full load and 60Hz is 5%, the harmonic voltage distortion input to the motor at full load is generally 5%

   Product Application

       1. Convert the PWM waves output by the inverter sine waves 
       2. Reduce the eddy current losses of the motor and the motor noise 
       3. Reduce the pulse current of the output cable and motor, extending the life of the motor" 
       4. A longer cable wire can be used between the inverter and motor 
       5. Reduce the external radiation, by using unshielded cable in certain situations, lowering  the requirements for on-site wiring requirements 
       6. Effectively prevent fatigue damage of the motor cau
