Thread: Another vsd question

Firstly I doubt that a 240V VFD exists. and done;t forget the +/- 10% is almost certainly just a guide.

Here in WA, over the last few weeks I have been seeing 250+V on a regular basis. It doesn't seem to bother the VFDs at all.

If you purchase a quality VFD that hopefully means they use components that can handle greater electrical stresses so if in doubt consider purchasing a quality brand.

The nominal voltage in Australia is 230V +10% -6%.
WA, Qld and ACT still specify 240V. I think. They may have come into line now. But it's only the official voltage level.
Your power supply will fluctuate with changes in the load on the overall system. Hence the +/- % values.

All that aside, a 220V rated unit will be fine for use in Australia. Most, if not all, 220V rated equipment is manufactured to withstand and operate at at higher and lower voltages and will have a similar +/- % rating.

Thanks for your replys I brought a quality 0.55 kw drive to power the 1/2 hp motor that will be going on the grinder. (220-240).

Mark.
