Frequently asked questions
What is the difference between constant voltage and constant current mode on this supply?
In constant voltage mode the supply holds the set voltage while the load draws what it needs up to the current limit. In constant current mode it holds the set current limit and lowers the voltage if the load demands more, which is useful for protecting a circuit during first power-up.
Can the two channels be used in series or parallel?
Yes, the listing states that the supply supports series and parallel operation. Series connection doubles the voltage and parallel connection doubles the available current, so confirm the wiring and the protection settings in the manual before connecting.
