Output 1 is under normal conditions regulated to Vo1 nom,
independent of 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 the value of Vo1.
The following 3 figures show the regulation with varying load
distribution.
Two outputs of an S2000 model connected in parallel will behave
like the output of an S1000 model.

Output Voltage Regulation of Double Output Models
Note: If output 2 is not used, we recommend connecting it in
parallel with output 1. This ensures good regulation and efficiency.
