Yes its 120v at the wall, but what Im suggesting is that its not a different motor block from the SDC pumps, but rather includes an onboard package to drive the pump at a predetermined max setting and allow for simplicity of use for those that have only a need for an efficient return pump sans any user accessible controls.The AC version is as expected 120v but the DC is 24v. The windings I would assume would have to be different to handle the higher amp draw.
This one is a controllable AC pump.
I would be interested in knowing if this pump has a chip in the block as well or built in the controller.

From what @Brew12 has learned from his sales guy it may very well be feasible cost wise for sicce to do this since they've already invested in the really expensive hardware R/D and production apparatus for their flagship SDC line. I can see why they might offer a simpler plug and play line for customers not into having any extra control options. This would increase production volume and subsequent cost effeciency per unit of their bldc motor blocks. Starting to make a lot of sense to me. And personally, running a service biz myself with upwards of 100 centrifugal pumps in the field, I pass on anything with a power brick or controller 100 percent of the time. Only in-tank wavemakers and lights are allowed to have those in my fleet. Too much at risk for primary life support to have any extra points of failure imo, so I can see the value in this pump for customers who want simplicity. I'll be sticking to my 1262s, iwakis, panworlds, and askoll built pumps for the forseen future. May try out one of these ADVs in a noncritical application for fun though.
