    Yes, that is correct.

    power supplies that have both voltage and current controls work in one of two ways.

    Some have a mode switch that you set to constant voltage or constant current. When in constant current mode, it adjusts the voltage to achieve that exact current.

    Others have a voltage setting and a current limit. In this case, the voltage stays at the setting until the current limit is reached, then it lowers the voltage to keep the current at the limit.
