There is no functional difference between AP9630, AP9631, or AP9635 and their CH SKU counterparts. Both sets of SKUs utilize and support the same firmware applications.
To summarize, the only main difference is that the -CH SKUs have been modified to showcase the Schneider Electric brand on their front faceplate.
Please note that as of the 5.1.7 and higher firmware releases, all AP9630 and AP9631 SKUs have Schneider Branded faceplates (and network interfaces) and ultimately, there will be no difference between the two SKUs except that AP9630CH and AP9631CH were initially intended for China only.
