Have you measured the o/p voltage? ..Clive
That's my understanding too. There is no jumper, therefore its set to 220V.

I wired it directly last night as I wanted the CS Labs controller to stay powered, even when the 110V drops out for whatever reason. So I connected it to 220V and a bit later, the PSU greeted me with some smoke. I should have measured the voltage prior to connecting up but there is no jumper, I checked this, which means 220V input is OK.

Clearly not .... Maybe both of us have the wrong way of thinking of this link / jumper. Just to confirm, that pic was taken before anything was changed and shows all wiring as it was. There is no jumper / bridge. I checked the unit again this morning before coming to work.
