Frequently Asked Questions
Can I use the HLG-320H-C1750DA for DALI-controlled LED street lighting?
Yes. The HLG-320H-C1750DA provides 1750mA constant current at up to 320.25W with DALI-2 digital dimming. Its IP67 waterproof rating allows direct exposure to rain, snow, and temporary flooding inside street light poles or fixture housings. The DALI bus enables centralized scheduling, dimming, and monitoring across multiple luminaires.
Is the HLG-320H-C1750DA suitable for outdoor LED floodlights at a sports field?
Yes. The 320.25W output at 1750mA can drive high-power floodlight LED modules with string voltages in the 91-183V range. The DALI-2 interface lets a central controller dim or switch fixtures for different event lighting scenes. The IP67 enclosure withstands direct weather exposure at the top of lighting poles.
Can I integrate the HLG-320H-C1750DA into a smart building lighting network?
Yes. The DALI-2 interface allows individual addressing, group control, and scene management through any DALI-compatible building automation system. This supports daylight harvesting, occupancy response, and scheduled dimming profiles. The driver responds to standard DALI broadcast and addressed commands on the two-wire bus.
Can the HLG-320H-C1750DA be mounted in a location that may flood temporarily?
The IP67 rating means the unit is dust-tight and can withstand temporary immersion in water up to 1 meter for 30 minutes. It can handle brief flooding events, but it is not designed for permanent submersion. For installations near water features or in flood-prone trenches, ensure drainage is adequate and submersion duration stays within IP67 limits.
How do I confirm the HLG-320H-C1750DA will work with my LED modules?
Check that your LED modules require 1750mA drive current and that the total series string voltage at that current falls within 91-183V. Also verify your DALI controller supports DALI-2 device type 6 (LED gear). The driver automatically adjusts voltage to maintain 1750mA through the connected LED load.
How does the HLG-320H-C1750DA differ from the HLG-320H-C1750B?
Both deliver 1750mA at up to 320.25W with the same 91-183V CC range. The key differences are dimming protocol and IP rating. The -C1750B uses analog 1-10V/PWM dimming and is rated IP65 (water-jet resistant). The -C1750DA uses DALI-2 digital dimming and is rated IP67 (waterproof, temporary submersion). Choose DALI for digital building networks and -B for simple analog dimming.
