The analogue monitoring outputs put out 0...10V which
corresponds to 0...100% of the nominal values.
Reference is analogue ground (AGND).
Set values 1
Analogue inputs (AI)
The example shows how the set values can be con-
trolled using the reference voltage (10V, VREF) and
potentiometers on the set value inputs.
The potentiometer should be 10kOhm each or hig-
her.
Set values 2
Analogue inputs (AI)
The example shows how to control voltage and cur-
rent by means of external voltage sources.
Attention! Never connect voltages >12V to these
inputs!
Set values >10V are clipped to 100% nominal va-
lue.
