DC Outputs

Looking at the results of the DC output, we have to say that this is not a great performance. Every rail shows a high drop of at least 3 to 4% - this is of course still within the specification but not ideal. The problem might lie with the six 12V rails that will in most cases not be connected all together. If you load all of the six rails exactly according to the diagram it will look better but if you connect only three of the rails for example it will look similar to the above graphics. The 12V rail doesn't look too bad and has a deviation of up to 3%, but the lower voltage rails have a wider range of a little more than 4%.
