Have noted that IEC61293 is referenced in 60601, but is not in 1010 or 950. Do not understand because 61293 is published in LVD, but not in MDD.
Believe that 61293 says that the 'x/y' rating for a power supply indicates that must be manually switched between the various voltages. How does that affect a power supply rated for auto-sense (no user select required)? Unless we have a phrase or symbol to indicate an auto-sense and a user-selected input, can we consider 61293 harmonized? We make some stuff that is rated 120/240, or 100-120/200-240 - but can be plugged into 85V to 265V with no user select. Doug Powell advised use of '!' notation for user manual. Other ideas? Also, why such a long time to stability date? Typically 3 to 5 years?

Didn't we discuss this here only a week or so ago? In a nutshell, 115/230 means you have to change a setting: 115-230 means you don't, but it doesn't guarantee that the product will work on some weird intermediate value such as 160. There IS a standard, not well known: IEC 61293 Edition 1.0 (1994-06-22) Marking of electrical equipment with ratings related to electrical supply - Safety requirements Stability Date: 2016 -- OOO - Own Opinions Only.
