The Dali dimmable driver is a constant current driver and is suitable to be used with the round or rectangular panels.
All the drivers have the same voltage range and the same connector to fit the panels. This means that any panel can be equipped with any driver as long as the nominal power of the driver doesn’t exceed the nominal power of the panel. If a panel provides to much light, one can either use a dimmable driver or if dimmability is not required, simply a lower power driver can also be suitable. The 1-10V dimmable drivers source current on the controlling wires, thus making possible to dim them also with variable resistors.
