Frequently Asked Questions
Can I use the HLG-320H-C2800AB for dimmable warehouse LED high-bay lighting?
Yes. The HLG-320H-C2800AB delivers 319.2W at 2800mA with both adjustable output and dimming input (1-10V, PWM, or resistance). This combination lets you set a baseline output level with the potentiometer and then dynamically dim via an external signal, which is ideal for warehouse occupancy- or daylight-based dimming.
Is the HLG-320H-C2800AB a good choice for sports field LED floodlights with dimming?
It can power high-output floodlight modules operating within its 57-114V CC range at 2800mA. The dimming input allows reducing output for practice sessions versus competition lighting. However, its IP65 rating means it should be mounted in a sheltered enclosure if directly exposed to heavy rain.
Can I use the HLG-320H-C2800AB for large-format LED signage that needs brightness control?
Yes. At 319.2W and 2800mA, it has enough power for large sign modules in the 57-114V range. The built-in dimming lets you reduce brightness at night to comply with local light-pollution regulations or save energy, while the adjustable output trims the baseline to match your exact module configuration.
What is the difference between the A, AB, B, and DA variants of the HLG-320H-C2800?
All four share the same 319.2W / 118V / 2800mA core specs with a 57-114V CC range. The -A has an adjustable potentiometer only (IP65). The -AB adds both adjustment and 1-10V/PWM dimming (IP65). The -B provides dimming only (IP65). The -DA replaces analog dimming with a DALI digital interface and is rated IP67 waterproof.
How many LEDs can the HLG-320H-C2800AB drive in series?
The number depends on each LED's forward voltage. With a CC voltage range of 57-114V at 2800mA, divide your desired string voltage by the individual LED forward voltage. Ensure the total string voltage remains within 57-114V for proper constant current regulation.
Is the HLG-320H-C2800AB rated for dusty industrial environments?
Yes. The IP65 rating means the enclosure is dust-tight (no dust ingress) and protected against low-pressure water jets from any direction. This makes it suitable for factories, workshops, and dusty processing areas. The -40°C to +85°C operating range also covers harsh thermal conditions.
