Quoted from shlt_thunder:Question. If we are already using a power spitter for the expressive light kit, are we going to need another power spitter for these lights? If using both and the topper, how might you get power to all of those things at once?
You can definitely split the splitter on one side with another splitter (barely avoiding a "yo dawg heard you like..." meme here.) As stated in the listings, each of these draws under an amp from the 48v, and the power distribution board shouldn't have any problem handling two of them. What I do NOT know is how much current the topper draws. I suspect not a lot, but I have no data for that. It is possible that the combination of the 3 may be pushing it for the power board, but I honestly don't know. The 10.5A capacity of the main 48v power supply should also be able to handle all of this (the cooling fan may run more often, but the power supply should safely manage any overcurrent situation without receiving or causing any damage), but again... "should" is not a "definitely!" As with any mod you make or install, you're taking the risk on your own, but this is a definitively gray area without knowing the power draw of the toppers. What I can definitely say is that the wire I use for the splitters can safely handle well over 20A, and the CN7 Molex connector/pins are rated to at least 13.5A, so those will not be your bottlenecks.
To be clear, this isn't me saying "do it!!" so much as I'm saying "while it should work, we make no such guarantee and you are responsible for any damage to the game and/or accessories caused by this".
The surefire solution would be to get an additional dedicated 48v power supply, wire it into the incoming AC mains power, and power your accessories off of that. I can give you part numbers for the molex plugs you would need to do this. In fact, let me just do that right here:
Molex Plug (female, replicates the CN7 socket): 0050842022
Pins for that plug: 0002081002
And should you need it, the male plug (plugs into CN7) is: 0050841025
With Pins: 0002082004
With those you could build pigtails from a second 48v power supply that our light kits could plug right into. Or you could build a test rig to interrupt the power to the topper so you can take some meaningful current draw measurements to determine exactly how much load the topper is pulling... though even that won't 100% answer the question because Stern doesn't publish current draw limits for CN7 on the power board, though I suspect it has plenty of capacity to go around.
I hope that helps, in a roundabout sort of way where I'm gracefully refusing to actually answer your question.
