MEAN WELL HLG-600H-20A is a Type A constant-voltage plus constant-current LED driver rated for 20VDC at 28A and 560W total output power. The Type A configuration has an IP65 metal enclosure and lets the output-voltage and output-current levels be adjusted through built-in potentiometers. It is not the 3-in-1 dimmable B or AB configuration.Technical details below were checked against the MEAN WELL English series datasheet. Confirm final wiring, protection coordination, enclosure design, cooling, and derating against the datasheet before system integration.Features Constant-voltage and constant-current output - Rated for 20VDC at 28A, with 560W total output power and a constant-current region of 10-20V. Type A adjustable output - Built-in potentiometers provide the documented 16.5-20.5V output-voltage range and 14-28A output-current range. Wide AC/DC input - Accepts 90-305VAC or 127-431VDC input at 47-63Hz according to the MEAN WELL English datasheet. Active PFC - The datasheet lists PF at least 0.98 at 115VAC, at least 0.95 at 230VAC, and at least 0.93 at 277VAC under full load. IP65 metal enclosure - The Type A model is rated IP65. Confirm the installed system, cable exits, mounting, and enclosure design for the intended environment. Fanless cooling - Fanless free-air convection design with a specified -40 to +90C maximum case-temperature range; follow the datasheet derating curve. Remote standby function - The series lists remote ON/OFF control and standby power consumption below 0.5W at remote off. Protection functions - Includes short-circuit, over-current, over-voltage, and over-temperature protection. Warranty - MEAN WELL lists a 7-year warranty for the HLG-600H series.
