Frequently Asked Questions
Can I use the HLG-320H-C1750AB for LED high-bay fixtures with dimming in a warehouse?
Yes. The HLG-320H-C1750AB delivers 1750mA constant current at up to 320.25W, suitable for high-bay LED modules with string voltages in the 91-183V range. The built-in 1-10V/PWM dimming input lets you integrate occupancy sensors or daylight harvesting controllers for energy savings during off-peak hours.
Is the HLG-320H-C1750AB suitable for driving LED panels in a large open-plan office?
Yes, provided the LED panels require 1750mA drive current and their voltage falls within 91-183V. The adjustable output lets you fine-tune current to match the specific LED module, while the dimming input enables smooth brightness control through a 1-10V or PWM signal from a lighting controller or building management system.
Can the HLG-320H-C1750AB power LED modules in a greenhouse lighting system?
Yes. The 320.25W output at 1750mA is well suited for horticultural LED fixtures operating within the 91-183V range. The adjustable current output lets you match specific grow-light module requirements, and the dimming input enables automated light-level scheduling. Its IP65 rating provides adequate protection in humid greenhouse environments.
What is the advantage of the HLG-320H-C1750AB over the C1750A or C1750B?
The HLG-320H-C1750AB combines both features of the other variants: it has the output current adjustment potentiometer from the -C1750A and the 1-10V/PWM dimming input from the -C1750B. This gives you both permanent current calibration and dynamic dimming control in a single unit, all at the same 320.25W / 1750mA / 91-183V specs and IP65 rating.
How do I verify the HLG-320H-C1750AB is compatible with my LED load?
Confirm your LED module or series string requires a 1750mA drive current and that its total forward voltage falls within the 91-183V range. The driver will auto-regulate voltage to maintain constant current. If your LEDs need slightly less than 1750mA, use the built-in potentiometer to reduce the output current to the optimal level.
Can the HLG-320H-C1750AB be used in a covered outdoor car park?
Yes. The IP65 rating protects against dust ingress and low-pressure water jets, which is adequate for covered or semi-enclosed parking structures. The operating temperature range of -40°C to +85°C handles seasonal temperature extremes. For uncovered areas with direct rain exposure, the IP67-rated HLG-320H-C1750DA is a better choice.
