VFD 220v single phase to 380v three phase.

Neale, Drives Direct are more than willing to provide you with such a setup new, at fantastically wallet emptying prices.

I have looked at building something, but I've never been able to find what VFDs are suitable for online/load switching.



There's no fun in that!

I spoke to Direct Drives. Pricy and when you mention CNC they say 'no sure if that load would work'. So clearly too risk / pricy to experiment.

Not quite sure what CNC has to do with it! At least some of the 240-415 inverters on their eBay site come with remote control pods and external CNC control is effectively only replacing the remote controls in the box. But at £600+ for a 3HP box, it's a bit steep.

Thanks for the offer of letting me look at one of the Ecogoo systems but at 200miles distance in South Devon it's a bit far. Kind offer, though. From your experience it sounds as if one of these would suit me anyway, so I'll see what Father Christmas puts in my stocking. Or at least I'll see what's left in my wallet the other side of Christmas!

I think its due to the load being variable and possibly 'choppy' if you think that the drives are doing their own trickery.

No problem, always welcome. We are property hunting and whilst your area is appealing, not sure we will head out that far. One of my team members at work lives in South Moulton.
