The sprint 400 is: 110/240 = 90/180
So: 110v = 90v and 240 = 180v

The switch is just an input voltage selector like on a meanwell power supply.
However. Unlike a meanwell, a speed control is relative to it's input.
So if it gets 240v it'll put out 100%. If it gets 110v it'll only put out 50%.
Ergo 180/90.

Unless you have the actual 180v version motor for it I'm afraid you likely need the KB.
(basically a bodged voltage board worked out cheaper to get u.k. sales)

Yours may look the same to others but they'll likely have the 180v motor too.

I may have updated previous post too while you responded.
Ah, this might explain why I can only get 100V out of it. Hmm. There do seem to be fairly cheap PWM DC-DC controllers on Ebay which I could maybe bolt on
