DRIVING METHODS OF LED MODULE
40W Constant Current Mode LED Driver
※ This series works in constant current mode to directly drive the LEDs.
Typical output current normalized by rated current (%)
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.
