Frequently Asked Questions
Can I use the HLG-320H-C2800B to power dimmable LED high-bay fixtures?
Yes. The HLG-320H-C2800B provides 319.2W at 2800mA constant current with a built-in dimming interface (1-10V, PWM, or resistance). It can drive high-bay LED modules whose string voltage falls within the 57-114V range, and the dimming capability supports occupancy-based or scheduled brightness reduction.
Is the HLG-320H-C2800B suitable for LED street lighting with photocell dimming?
Yes. The dimming input accepts 1-10V or PWM signals, which many photocell dimming controllers output. At 319.2W and 2800mA, it can power street light modules in the 57-114V range. The IP65 rating handles outdoor dust and rain spray, though it should be mounted in a pole-top enclosure for best protection.
Can the HLG-320H-C2800B drive LED fixtures in a cold-storage facility?
Yes. Its operating temperature range of -40°C to +85°C covers cold-storage and freezer environments. The 2800mA constant current output at up to 319.2W can drive high-output LED luminaires, and the dimming input allows reducing light during non-working hours to save energy.
Will the HLG-320H-C2800B work for illuminated LED advertising displays?
Yes, provided the display modules operate within the 57-114V CC voltage range at 2800mA. The built-in dimming input is useful for reducing brightness at night. At 319.2W total output, it can handle large illuminated sign panels or backlit display cabinets.
How does the HLG-320H-C2800B differ from the HLG-320H-C2800A?
Both share identical core specs: 319.2W, 118V, 2800mA, and a 57-114V CC range with IP65 protection. The -B model includes a dimming input (1-10V/PWM/resistance) but no output adjustment potentiometer. The -A model has an output adjustment potentiometer but no dimming input. Choose -B for external dimming control or -A for fixed output trimming.
Can the HLG-320H-C2800B be mounted in an outdoor junction box?
Yes. Its IP65 rating protects against dust ingress and low-pressure water jets, making it safe for outdoor junction boxes, electrical cabinets, or covered mounting locations. For fully submerged or heavily flooded installations, the IP67-rated DA variant would be more appropriate.
