  • 3hp Vfd Variable Frequency Drive - USA

    price: contact company for price

    My understanding is that the IEC EMC committees are working on this very

    issue. Even when they have something it is likely that the VFD

    manufacturers will have lobbied hard to ensure it is not too difficult

    to meet. And we will still have the trouble.

    What is the carrier frequency setting of your 3hp VFD? Have you considered lowering it? Also look at setting skip frequencies the in your motor' s or systems resonant frequencies. What harmonic precautions have you put in place?

    If the 3 hp VFD is over rated for the ID fan load you can simply increase the carrier frequency provided it' s not already beyond 6kHz. The skip frequencies can be implemented, however depending on the control scheme might not work for your application of this 3hp VFD.
