Re: Old 883= 24V Speed controller???
It's been a while, so I may be wrong on this, but I seem to remember that IFI made both 12V and 24V 883s (and FIRST teams were supplied with 12V 883s, since FIRST has never used 24V systems). The difference between the 883 and the 884 had something to do with deadbands.

EDIT: Okay, I looked it up, and I was partially correct. The 883 can take between 6V and 30V, but the fan on top of the FIRST models could only take 12V. However, if you use two, you can wire the fans in series. The 884 has a greater dynamic range (3%-100% as opposed to 10% to 100%), and an added deadband to compensate.

EDIT: Read SandDrag's comments below. I may have been looking at the wrong datasheet.
