Basically it boils down to the ratings that they use. MOSFETS have several ratings some are continuous and others are pulsed. The pulsed rating is the higher of the 2. Temp plays a part in it as well that's why there is a derating curve for the Fets. The hotter they get the less efficient and power they can handle. If you look at that I think that Novak rates theirs based on Burst current. If you look at the MMM it's rated at 120A but the burst current was somewhere near 1000A.

I seriously doubt any of the speed controls will handle what they are rated anyway. If you draw 100A at 12V on a MM I doubt it would last more than a few minutes. Same with the MMM If you were to load it at 22V and 120A even with the fan in an A/C room set at 72F it wouldn't last more than half an hour. Granted these things run off of batteries, but to me a continuous rating it just that...

It must be understood that common sense and caution are factors which cant be built into this product. Last edited by J57ltr; 08.31.2009 at 12:33 PM.
