Frequently Asked Questions
Can I use the HLG-320H-C1400DA to power LED street light fixtures with DALI control?
Yes. The HLG-320H-C1400DA outputs 1400mA constant current at up to 320.6W and supports DALI-2 digital dimming, making it ideal for smart street lighting systems. Its IP67 waterproof rating means it can be mounted inside pole bases or fixture housings fully exposed to weather.
Is the HLG-320H-C1400DA suitable for outdoor LED floodlights in a parking lot?
Yes. The 320.6W output at 1400mA provides ample power for high-output LED floodlight modules whose string voltage falls within the 114-229V range. The IP67 enclosure handles direct rain, snow, and temporary pooling, and the DALI interface enables centralized dimming schedules for energy management across the lot.
Can I integrate the HLG-320H-C1400DA into a building management system?
Yes. The DALI-2 interface on the HLG-320H-C1400DA allows integration with DALI-compatible building automation controllers. This enables scheduled dimming, daylight harvesting, and occupancy-based control. The driver can be addressed individually or as part of a DALI group on a shared two-wire bus.
Can the HLG-320H-C1400DA drive LED arrays for large illuminated signage outdoors?
Yes, provided the LED string voltage at 1400mA falls within 114-229V. The 320.6W capacity supports demanding sign loads, and the DALI control lets you remotely adjust brightness. The IP67 waterproof rating protects the driver in exposed outdoor enclosures without additional weatherproofing.
How do I determine if the HLG-320H-C1400DA is compatible with my LED load?
Verify that your LED module or string requires 1400mA drive current and that its total forward voltage falls within the 114-229V constant-current range. The driver will automatically adjust its output voltage to maintain 1400mA through the load. Also confirm your DALI controller is DALI-2 compatible for full dimming functionality.
Can the HLG-320H-C1400DA withstand installation in a coastal environment?
The HLG-320H-C1400DA is rated IP67, meaning it is dust-tight and can handle temporary immersion in water. Its aluminium casing and -40°C to +85°C operating range provide robust protection. In highly corrosive salt-spray environments, additional protective measures such as a secondary enclosure or conformal coating are still recommended.
