Adjust set values 1
Inputs: VSEL and CSEL
This example shows how the set values can be
adjusted using the reference voltage (10V, VREF)
and potentiometers on the set value inputs.
The bridge between pin 10 and Pin 7 switches the
device to the required remote control mode. This
bridge can be substituted by a low resistive switch.
In case only one of both set values shall be adjusted,
the other one should be tied to pin VREF.
The potentiometer should be 10kOhm each or
higher.
Adjust set values 2
Inputs: VSEL and CSEL
The example shows how to control voltage and
current by means of external voltage sources. Also
see example 1.
Attention! Never connect voltages >12V to these
inputs!
Set values >10V are internally clipped to 100%
nominal value.
