Sink-source mode switching
The switchover between sink and source mode happens automatically and only depends on the device’s voltage
setting and actual value on the DC terminal or the remote sense connector, if in use.
It means, that when connecting an external voltage source to the DC terminal, only the voltage set value determines
the operation mode. When connecting a load which cannot generate a voltage, only source mode can be run.
Rules for applications with external voltage source connected:
•
If the voltage set value is higher than the actual voltage of the external source, the device will run in source mode
•
If the voltage set value is lower, it will run in sink mode
To run one of both modes explicitly, i.e. without automatic switchover, it would require following:
•
for “source only mode” adjust the current set value for the sink to 0
•
for “sink only mode” adjust the voltage set value to 0
