Frequently Asked Questions
Can I use the HLG-240H-54A to fine-tune drive current for 54V LED high-bay fixtures?
Yes. The HLG-240H-54A includes a built-in potentiometer that lets you adjust both output voltage and current. This is useful when your 54V high-bay fixtures need a specific drive level or when you want to reduce output slightly to extend LED lifespan across the 27-54V CC range.
Is the HLG-240H-54A suitable for powering 54V LED floodlights in a covered parking structure?
Yes. At 240W and 54V with IP65 water-resistant protection, the HLG-240H-54A handles dust and low-pressure water jets typical of parking garages and covered canopies. The adjustable output lets you match the driver precisely to the floodlight's optimal forward voltage.
Can the HLG-240H-54A power 54V LED modules in an indoor retail display installation?
Yes. The HLG-240H-54A delivers up to 240W at 54V with adjustable output, allowing precise tuning for retail display lighting where consistent color temperature and brightness are important. Its aluminium casing and compact dimensions of 244.2 × 68.0 × 38.8 mm allow concealed mounting above ceiling tiles or in service cabinets.
How many 54V LED modules can I run from the HLG-240H-54A?
The total combined wattage must not exceed 240W. For example, if each 54V module draws 48W, you could connect up to five modules (5 × 48W = 240W). Always check each module's rated power consumption and keep the total at or below the driver's 240W capacity.
Can the HLG-240H-54A be used in a damp equipment room or ventilated outdoor enclosure?
Yes. The IP65 rating protects against dust ingress and low-pressure water jets from any direction, making it suitable for damp equipment rooms, ventilated outdoor cabinets, and covered canopy installations. For locations with direct rain or potential water immersion, consider the IP67-rated HLG-240H-54 or HLG-240H-54B instead.
