PS 9000 1U Series
In case the DC output is already switched on, toggling the pin will switch the DC output off, similar to what it does
in analog remote control:

b) Remote control of current and power
Requires remote control to be activated (Pin "Remote" = LOW)
The set values VSEL and CSEL are generated from the reference voltage VREF, using potentiometers for each.
Hence the power supply can selectively work in current limiting or power limiting mode. According to the specifica-
tion of max. 5 mA for the VREF output, potentiometers of at least 10 kΩ must be used.
The power set value PSEL is always tied to VREF and will thus be permanently 100%.
If the control voltage is fed in from an external source it is necessary to consider the input voltage ranges for set
values (0...5 V oder 0...10 V).
Use of the input voltage range 0...5 V for 0...100% set value halves the effective resolution.
Example with potentiometers
c) Reading actual values
Via the AI, the DC output values of current and voltage can be monitored. They can be read using a standard
multimeter or anything else that records analog signals.
