2) Example with external voltage source/potentiometers control
Consider the input voltage ranges to select the input reference voltage (VREF), 5V or 10V.
Then adjust the external voltage input (0~5V) or external potentiometer (0~5kΩ or 0~10kΩ)
to remotely adjust the power supply voltage and current regulation settings.

Application examples
1) Enable the external control with low level
Change the signal polarity setting of 'EXT-EN' to 'L' in the menu accordingly will enable external

3) Reading the actual values
Consider the standard multimeter range to select the Output reference voltage (VREF), 5V or
10V. Use a standard multimeter or similar to monitor the actual output voltage and current.
