480W Constant Current Mode LED Driver
HLG-480H-C series
File Name:HLG-480H-C-SPEC 2018-09-30
DRIVING METHODS OF LED MODULE
In the constant current region, the highest voltage at the output of the driver
MEAN WELL Environment Adaptive Function allows the driver to detect
depends on the configuration of the end systems.
and automatically adjust the output up to 120% Vo with 80% Io and turns
Should there be any compatibility issues, please contact MEAN WELL.
