If they are NOT fully isolated, and I tried to chain them together, what would happen?
BOOM!
Guess I'm not trying that then.
Or am I...?
(/jk)
Is there any kind of cheap hack that would allow me to test it to find out if it is fully isolated?
Test the impedance between the AC input and the DC output.
Also if the big cap that I see in the pics is rated at 400v it's very very likely the thing is not isolated.
Also post the code on the IC and any other transistors/IC's you see.
Impedance between the AC in and DC out is infinite (in all combinations).
The caps are 400v and 4.7uF.
ICS:
1. AVM40B
2. LB5M - 4B37
3. ES1D (I think this is a diode? It has a "D2" beside it on the board.)
PS what are you trying to power with them chained together ?
I need 36V for some 100W LEDs:

Forward Current: 3000 mA
My DIY benchtop power supply will only kick out 26~27V, so I need to boost that up to 36V with a booster that I have, but I'd like to try something else that I can put in an enclosure. These are some of what I have, and I was wondering if I could manage it.
I have 8 of those LEDs, and would like to get them all powered up in an array. (Or as many as I can manage.)
I know that's an insane amount of light. The answer to "why" is "because I'll learn something along the way".
