Low operating temperature leads to increased lifetime.
The uncontrolled ports supply continuous current, even when the driver is switched off. Important for the linear lights with integrated switching function (PL4001, PL4005, PL4006).
6 controlled output ports + 2 uncontrolled output ports (uncontrolled output ports feature constant power even if the driver is switched off; important for linear lights with integrated switch (PL4001, PL4005, PL4006))
