Hi do you have schematic of your wiring? It seems complex looking at the wires. I am not sure how your key switch connects and operates in the system .
The very first component in that little AC/DC power supply is a full wave rectifier which converts the input AC voltage to a DC voltage. If you apply a DC voltage directly to the input, the positive polarity diode in the full wave rectifier simply passes the DC voltage to the DC filter stage with the only loss being the forward voltage of the two diodes. Ideally, you could pull the supply apart and bypass the FWR and wire the DC input directly to the DC filter stage, but at 100VDC input, the losses are so small that it would make no difference. Note that when 100VAC is full wave rectified to DC you end up with 1.414 times the DC voltage as the AC applied voltage (ideally) so if you use DC input voltage, it may not work correctly unless it's ~1.4 times the minimum AC input voltage range.
Question about your throttle. Typically these controllers need a 5K ohm throttle, but when I research them the Magura is over $100. That throttle you have is well under that, but all the listings I see for it don't say it's a 5K ohm throttle. Did you just figure out which leads on the throttle are the potentiometer and run with it?
I actually didn't think much about the throttle - pretty sure this controller can use a potentiometer-based throttle or one that is voltage-based. The throttle Im using is voltage-based. I measured the range at one point but forget what it was. Either way you should be able to use a cheap ebike throttle and dial in the range when programming the controller

How to put a mode selector
Where did you get the controller from?
purchased directly from kelly controller but their website has been down lately kellycontroller.com/
did you ever find out the answer to the ac-dc buck converter trivia question?
