PS407 AC voltage tolerance - documentary сonfirmation

Good day.

I can't find any documentary сonfirmation for "Simatic S7-400, PS407:10A, 6ES7407-0KA02-0AA0" input AC voltage tolerance.

1. Datasheet does not give this information.

2. I found some information on the forum (https://support.industry.siemens.com/forum/nl/en/posts/pcs7-power-supply-tolerance/31398/?page=0&pageSize=10) - thanks to Daniel Chartier.

"• Permissible range 88 to 300 V AC 85 to 264 V DC (varying voltage input)"

But URL (http://support.automation.siemens.com/WW/view/en/1117740) leads to a page with an error.

And I need to find confirmation of this value in official sources (the device will actually be tested at 207 Vrms and 253 Vrms input voltage).

Perhaps this information is in some catalogs or in the EMC test reports?

 Hello,

I believe you swapped the AC and DC limits!!

The correct permissible limits are 85-264 V AC network or an 88-300 V DC

Please see section 3.7 & 3.2 in the below manual
