    Hi, everybody,
    Does someone know if it is possible to use a variable frequency inverter, made for controlling AC motors at 400V 50 Hz, on 230V 50 Hz ?

    Regards. Tuffe

    It depends upon the inverter. Some are manufactured with a wide range of input voltage as being acceptable.

    They are quite common for 3-phase motors. Just look up VFD (variable frequency drive).

    Edit: On re-reading your question, refer to the spec sheet for the controller. Most will have a low-voltage cut-off, so a 440V controller will likely not work on 208V.

    look into yaskawa drives. I remember reading a data sheet a while back for one of their drives that would accept 220V single phase and output 480V 3phase but the rating was small, only low power motors. I know those aren't the specific numbers you listed but their drives are pretty flewxible and you could probably get what you want by changing a few parameters in the drive. I can't remember the model#, sorry.
