1) CV Regulation
When the voltage drop between the (+) output terminal and positive
sensing point increases 1V, its voltage Load regulation must be add
another 5mV.
2) Output Noise
A voltage load regulation effects could be occurred by any noise
which interferes the output terminal of the power supply. Therefore,
it will be helpful to reduce the output noise by paralleling two sensing
circuit of (S+) and (S-) and separating each other adequately, then
connect a single end to the ground terminal of power supply. The
relative configuration is as follows:
