Again, when it comes to electricity, it may as well be written in Latin......it does not compute to me. Rating on it says something like 10a at 40c. Is that what you were asking about shrodinger?
40C is the operating temp, meaning it can run in 104F temps indefinitely
the current will look something like this 4.6-4.2/2.1 A which is the current at the various voltages, ie, 208-230/460 VAC
the drive must be derated or it won't last long, the HP is usually referenced to 3 phase
and here is why:
let's say the motor uses 4.2 A at 230 vac, so P = sqrt(3) x 230 x 4.2 ~ 1670 W
let's assume the drive is 90% efficient, so the input power must be ~ 1670/0.9 ~ 1857 W
the eqivilent single phase current to make the same 2 HP is 1857/230 ~ 8.07 A
the drive is rated for 3 lines/phases of current, you are only using 2 legs...
the diodes/rectifier, SS swithces/inverter are sized for 3 lines
side track: a VFD works as follows: takes the incoming 3 phase, makes DC, then chops it back to AC with a variable timed inverter
back on track
a 2 HP is sized for ~ 4-5A at 240/3, it will see ~8 with single phase, the components are overloaded
what size do we need?
equivilent 3 phase P = sqrt(3) x 8.07 x 230 ~ 3211 W, converted to HP = 3211/746 ~ 4.3 HP
use a 5 HP drive...
each line of the 5 HP can handle >8 A of current, the 2 HP can only handle ~4.5 or so
without sounding like a smart ass I do this for a living
this assumes a fully loaded motor (as should be assumed/sized) but under engineering supervision you can downsize if you know the load...
so the 3.5 HP may work in a grinder/polishing application, but not say a pump
