Product Q&A

Q:How does the Active Harmonic Filter work?

It monitors load current via CT, extracts harmonics using DSP, and injects equal and opposite currents via PWM signals to IGBTs to cancel out harmonics.

Q:What is the response time of the filter?

The response time is less than 15ms, ensuring rapid compensation for harmonic distortion.

Q:Can multiple units be used together?

Yes, the system supports 1 to 10 sets connected in parallel for larger capacity needs.

Q:What are the input voltage specifications?

The rated input wire voltage is 380V, with an acceptable range of -15% to +20%.

Q:Is the device suitable for noisy environments?

Yes, it uses intelligent air cooling and has a noise index of less than 56dB.
