Almost certainly a neophyte question. I'm trying to understand the difference between nominal voltage and operation voltage range. My intuition was that, for a given power supply, it would hold a voltage within a few volts (hence, it would have an operational voltage range within a few volts of it's nominal voltage).

So what I'm trying to understand, is why a device such as this has such a wide operational voltage range:
