Re: Question on remote VFD panel usage

Actually I was looking at the Teco MA7200 which (for a 2 HP VFD)
only costs about $20 more than the FM100. If there is a
disadvantage to the MA7200 drive, please let me know.

As for Harold & Dealers, they are great people, know them for
years. (They are located at the Brooklyn Navy Yard, we're located
at the Brooklyn Army Terminal)
