Not sure this is what you are looking for; but the 110-230V unit is rated as a range, so the tolerance would be below 110 and above 230. The 110/230 V has two distinct rating ranges, so the tolerances would be above and below 110 AND above and below 230VAC. That's the first thing that pops into mind, anyway.
PS: Who operates at 110VAC 50Hz?
