Exactly the same remark as D.Bertrand. I needed 1,250 mA at 12V to power my scanner, I will have to return the transformer. To avoid this, it would be that the technical description of the product on the site is a bit more precise. And the difficulty to find a sufficiently powerful transformer at a reasonable price, I wonder if I will not have to simply change the scanner, just because it has no power supply. Long live the consumer society!
