UPB Low Voltage Dimming

I've been lurking here for a while, thanks for the great info so far.

We will be moving to a new house next month and I want to install UPB throughout.
I have a few switches in our current home I've been playing with.
One of the items I've been looking at is LED undercabinet lighting.
The LED bars run on 24VDC from a dimmable power supply.

Here is my question.
The power supply specifies using a magnetic dimmer on the mains supply side.
It even recommends a Leviton slider model.
Most of the standard UPB switches state they work with induction loads.
But I've read elsewhere, not to use these switches with a magnetic transformer.

So, do you think I can use a standard UPB dimmer with these LED drivers?
I was under the impression the UPB dimmers are PWM rather than magnetic/resistance.
Is that correct? I know not to use them on motors like fans.

If I can't run the dimmer on the mains side, is there a hack to tap off just the PWM signal without the 120VAC that I can apply to the DC side?
The lighting company has manual dimmers for the DC side so I think this approach would work.

Thanks for any help and a great site.
 
Thanks!
I'll give it a try.

ETA: Just pulled out the docs to my SA switch (what a novel idea), and sure enough it says magnetic low voltage right there in plain English.
Duh!
