In the constant current region, the highest voltage at the output of the driver
depends on the configuration of the end systems.
Should there be any compatibility issues, please contact MEAN WELL.
※ This series is able to work in either Constant Current mode (a direct drive way) or
Constant Voltage mode (usually through additional DC/DC driver) to drive the LEDs.
