Frequently Asked Questions
Can I use the HLG-240H-54AB with a 1-10V dimmer to control 54V LED warehouse lighting?
Yes. The AB suffix means the HLG-240H-54AB has both output adjustment and a 1-10V/PWM dimming interface. You can connect it to a warehouse lighting controller that sends a 1-10V signal to dim 54V LED fixtures. The adjustable potentiometer also allows manual fine-tuning of voltage and current.
Is the HLG-240H-54AB a good driver for 54V tunable-white LED fixtures in an office?
Yes. The HLG-240H-54AB provides 240W at 54V with dimming capability, making it suitable for tunable-white LED systems that require variable current. The built-in potentiometer lets you calibrate the driver to the LED module's optimal operating point, while the dimming input allows scene-based brightness control.
Can the HLG-240H-54AB power dimmable 54V LED signage in a covered outdoor area?
Yes. At 240W and 54V with IP65 water-resistant protection, the HLG-240H-54AB is suitable for covered outdoor locations such as gas station canopies, bus shelters, and building overhangs. The dimming input allows scheduled brightness adjustments for nighttime vs. daytime operation.
How many meters of 54V LED strip can the HLG-240H-54AB drive?
That depends on the strip's rated power per meter. The HLG-240H-54AB supplies up to 240W at 54V. For example, if your 54V strip draws 19.2W per meter, you could run up to 240 / 19.2 = 12.5 meters. Always check your strip's rated power per meter and keep total wattage at or below 240W.
Is IP65 adequate for the HLG-240H-54AB in a location exposed to light rain under an overhang?
Yes. IP65 protects against dust ingress and low-pressure water jets from any direction. This is sufficient for locations under eaves, overhangs, or canopies where direct downpour is blocked. For fully exposed outdoor installations with potential water immersion, select the IP67-rated HLG-240H-54B instead.
What distinguishes the HLG-240H-54AB from the other HLG-240H-54 variants?
All four 54V models share 240W / 54V / 4.45A core specs. The base -54 has fixed output and IP67. The -54A adds potentiometer adjustment (IP65). The -54AB (this model) combines both adjustment and 1-10V/PWM dimming (IP65). The -54B has dimming only and retains IP67. Choose the -54AB when you need both manual calibration and remote dimming control.
