Frequently Asked Questions
Can I use the HLG-320H-C1050AB with a building management system to dim LED high-bay lights?
Yes. The AB suffix means this driver has both output adjustment and a dimming signal input (1-10V/PWM). You can connect it to a BMS or lighting controller for automated brightness scheduling while using the built-in potentiometer to set the maximum output level. It delivers 1050mA constant current at up to 320.25W.
Is the HLG-320H-C1050AB suitable for dimmable LED grow light panels?
Yes, provided the grow light panel accepts 1050mA constant-current drive within the 152-305V range. The dimming input lets you reduce light intensity for seedling stages or increase it for flowering, and the potentiometer allows fine-tuning the maximum drive level. At 320.25W, it handles demanding horticultural LED arrays.
Can I use the HLG-320H-C1050AB for dimmable outdoor LED area lighting?
Yes. With 320.25W at 1050mA and IP65 water resistance, it is well suited for outdoor area lights, pathway fixtures, or parking lot luminaires that require dimming capability. The -40°C to +85°C operating range handles seasonal temperature extremes in most climates.
Can the HLG-320H-C1050AB drive LED tunnel or underpass lighting with dimming control?
Yes. The 320.25W output at 1050mA constant current can power tunnel luminaires with high-voltage LED strings in the 152-305V range. The dimming input allows daylight-responsive brightness adjustment at tunnel entrances and exits, and the IP65 rating handles the damp conditions typical in tunnels.
How do I size an LED string for the HLG-320H-C1050AB?
configure your LEDs in series so the total forward voltage falls within 152-305V. The driver will regulate at 1050mA constant current regardless of where in that range the voltage settles. The number of LEDs depends on each LED's forward voltage — add them up and verify the sum is within the CC range.
What are the differences between the HLG-320H-C1050A, C1050AB, C1050B, and C1050DA?
All four share the same 320.25W / 1050mA / 152-305V CC core specs. The C1050A has output adjustment only (potentiometer, IP65). The C1050B has dimming input only (IP65). The C1050AB combines adjustment and dimming (IP65). The C1050DA uses DALI protocol dimming and carries an IP67 waterproof rating for fully exposed installations.
