In my experience, a system that gets its power from a power supply which for input has either a transformer or a switcher with a two port input across which is connected one hot line and one neutral line or two hots out of phase from each other, that system is a 'single phase' system. Even though two phases may be used as power input, the effectivity is to act as a single phase input and can operate that way as well.
In other words, if you can plug and chug with no problems by replacing an input consisting of two hots out of phase from each other by a single phase hot/neutral input, then you've got a single phase system. It's effectively what the primary 'sees', one phase and that's what's counts, AFAIC.
