Okay, but the current sensing resistor in this case is limiting the current to the Victor as well. So you can't fully test the Victor's power range like that. Plus I don't think they have the same on-state resistance so the Jaguar might drop more voltage. Might not matter for what you plan.

I thought you planned on powering the same load with both speed controls, because you started off in the singular tense in the first proposition post. Clearly, however, you intend to use 2 loads and that's just fine.

The only thing is that the terrible things (as you put it before) involved here are not really inductive or motors?

I sort of ask because while I understand the heat concerns entirely, obviously there are quite a few other concerns in the comparison.
