Specs for CW1/S heater replacement kit?

Does anyone have the specs for the PTC heater Prusa sell? https://www.prusa3d.com/product/cw1-s-heater-replacement-kit/ I'd love to know at least these: wattage, voltage, safety features, mounting hold pattern.

I've been thinking about building a combined filtration + heater system (sharing the same fan). I know these can be had for cheap on Amazon, but it'd be nice if I could just order some of the parts from a trustworthy source when I place my next Prusa order ...

The closest I can find is a notation in the specs for the CW1/S itself.  For "preheat/drying" it states power use at "<135W".   I'm guessing the fan and electronics use very little (maybe 5w?), so the heater is likely something a little less than 130W.

Awesome - thanks @ScottW. I guess 120W is a common rating for these things. I wonder if it's 12V or 24V.

I wonder if it's 12V or 24V.

Just a guess...  Assuming it consumes about 120W, that would be 10A at 12V.  But the largest fuse on the board is 7.5A.  That leads me to GUESS that it is 24V (and therfore 5A), but I cannot find confirmation of that anywhere.
