Awesome small VFD!
My VFD is quiet, the nameplate has most of the info you need, and the paint and finishes are well done. But for a hobby motor, this is exactly what you need, and it's cheaper than anything I've seen.

Yes, we have. Just the price will be higher than the regular 480V input voltage option.

Super fast logistics speed
I like to buy goods in the online store because of their fast logistics. Today I bought this 0.4kW single phase output frequency inverter from the online store. I bought it specifically for household power supplies and single phase AC induction motors.
