Wrth ddefnyddio cyflenwad pŵer wedi'i reoleiddio gan DC, wrth addasu'r foltedd, canfyddir na ellir addasu'r foltedd dim llwyth.
Some operators like to turn the "current adjustment" potentiometer to the left, so that the no-load voltage of the power supply cannot be adjusted. This shows his lack of substantial understanding of "current regulation". Because the power supply consumes a little current even if it is no-load, and if you turn off the "current regulation" to zero, even a small current will not be released, and of course the no-load voltage will not rise. Therefore, "current regulation" is generally not adjusted to zero (the above situation will not occur if it is adjusted to the right to about a quarter of a turn).
Dull gweithredu cyffredinol: Pan ddefnyddir foltedd allbwn y ffynhonnell a reoleiddir, dylid troi'r bwlyn addasu cyfredol yn glocwedd i'r diwedd a'i gadw. Addaswch y bwlyn addasu foltedd i reoli gwerth foltedd allbwn DC. Wrth allbynnu cerrynt fel ffynhonnell gyfredol gyson, trowch y bwlyn addasu foltedd yn glocwedd i'r diwedd a'i gadw. Addaswch y bwlyn addasu cyfredol i reoli gwerth cyfredol allbwn DC.
