MEAN WELL HLG-600H-24B is a Type B constant-voltage plus constant-current LED driver rated for 24VDC at 25A and 600W total output power. The Type B configuration has an IP67 metal enclosure and supports 3-in-1 dimming through 0-10VDC, 10V PWM, or resistance. It is not a Type A or AB model with built-in output-voltage and output-current adjustment potentiometers.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 24VDC at 25A, with 600W total output power and a constant-current region of 12-24V. Type B 3-in-1 dimming - Supports the documented 0-10VDC, 10V PWM, or resistance dimming methods. Confirm dimmer compatibility, wiring, and system behavior before installation. 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. IP67 metal enclosure - The Type B model is rated IP67. Confirm the complete installation, 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 a 5V standby output at 0.5A. Follow the documented electrical limits. 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.

How can the Type B model be dimmed?The English datasheet lists 3-in-1 dimming by 0-10VDC, 10V PWM, or resistance. Confirm the external dimmer, wiring, and load before installation. Does the B type have built-in voltage or current adjustment?No. The datasheet identifies built-in output adjustment as an A or AB type function. Type B uses the documented 3-in-1 dimming interface instead. What input voltage does it accept?The English datasheet lists 90-305VAC or 127-431VDC input at 47-63Hz. Is this LED driver suitable for outdoor use?The Type B model is rated IP67. Confirm the complete installation, cable exits, mounting, and environmental conditions before use. What is included?The packing list includes one MEAN WELL HLG-600H-24B LED driver.
