Output Regulation of Double-Output Models
Output 1 is under normal conditions regulated to Vo nom,
independent of the output currents.
Vo2 depends upon the load distribution. If both outputs are
loaded with more than 10 % of Io nom, the deviation of Vo2
remains within ±5% of Vo1. The following 3 figures show the
regulation with varying load distribution.
Two outputs of a double-output model connected in parallel
behave like the output of a single-output model.
Note: If output 2 is not used, we recommend connecting it in
parallel with output 1. This ensures good regulation and
efficiency.
