Guys,
Like I said (wrote) I'm sure there are special types available - and there is. But those "step-up" types from?Automation Direct is only available for ver small motors (1/4 and 1/2HP).
If anyone have?a link or model number for a VFD taking 230VAC single phase input and outputting 400VAC Three pahse capable of driving a 2kW motor I'd love to know about it.
Jeff,
A VFD is a switch mode type supply yes, but I'll stick to my original statement. "Step-up" types may be available but they are not the norm. You'd need some pretty beefy inuctors/transformers?for a multi kilowatt step-up converter.
I've comissioned drives from ABB, Lenze, Omron, Danfoss and a few other brands, none have been able to output a voltage higher than the input. That doesn't mean I'm saying drives than can doesn't exist, I'm saying it's not the norm. You can call it nonsense if you like. Please show me a couple of >1kW drives that does.
/Henrik.
