Selection Notes
The 6AV2128-3UB27-0BX0 pairs an expandable round-pipe support arm with an Extension Unit, so pick it when the installation needs to add distance or a second mounting point later without swapping the arm hardware. It draws the same 1.2A rated current and 28.8W typical input power as the standard MTP1900 PRO panel, so no separate power budget is needed for the extension. Where the mount never needs to expand, the fixed flange-top support arm version is the simpler and lighter choice.
