BLOCK DIAGRAM Fosc : 100KHz 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. DRIVING METHODS OF LED MODULE 40W Constant Voltage + Constant Current LED Driver HLG - 4 0H se r i e s Typical output current normalized by rated current (%) ※ 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.
