Are they swtichmode powersupplies? As in do they provide 240V and 110V or just 110V?

You're terminology is incorrect, what you're asking about is Voltage auto sensing, not switchmode.

Was gonna say wth myself but resisted. So much for that idea... Wink

Ya. 'Switch-mode' refers to how the power is controlled. It is chopped on-off very fast and the average on-time determines power out. Very efficient. Often used for DC regulators but also applies to AC systems eg a dimmer switch.

The other way to to it is using Linear control. Very clean output but bulky and not efficient as the voltage difference between the DC feed supply and output is directly impressed across power transistors and dissipated as heat.

My bad! That's what happens when you have a few too many beers. I was meaning if the AC input side of these (I think I read that the powersupplies are included) are both !10V and 240V either with a physical switch or accept AC input voltages in the 100-240VAC range.
