Sources and updates

Scope of this page: Only the AA90U-480B-R model/series and the listed source-supported attributes. Series maximums or model-dependent ranges are identified in the conditions; options and prices are not inferred. Original revision date is printed 1/6/2025 and retained verbatim without guessing day/month order. Model tables share AA90 W and AA90U columns; only the AA90U input configuration is counted. Website nominal90 W labels and exact PDF wattages differ slightly for 19 V and 54 V models, so output watts are omitted rather than silently selected.
