Notes:
1) Up to the highest supply voltage that maintains shaft power less than the product power rating, for a typical induction motor. Derated for operation above this supply voltage.
2) Products take less input current when operated in these modes, than stated.
3) Based on a permanent-magnet motor with efficiency 90% and power factor 0.9.
