Mean Well HLG-240H-48A Power Supply 240W 48V - Adjustable

Yes. The A suffix indicates a built-in potentiometer for output voltage and current adjustment. This lets you fine-tune the drive level to match the exact forward voltage of your 48V quantum boards or COB LEDs, optimizing light output and thermal performance within the CC range of 24-48V.

Yes. The IP65 water-resistant rating protects against dust and low-pressure water jets, which is sufficient for covered parking garages, carports, and similar sheltered structures. At 240W and 48V, it can power long runs of 48V strip with minimal voltage drop. For fully exposed locations, consider the IP67-rated HLG-240H-48.

Yes. With 240W at 48V and 5A output, it handles substantial 48V sign module arrays. The adjustable output lets you dial the voltage to precisely match your module string, reducing wasted power. The IP65 rating is well suited for sign cabinets that have drainage but are not fully waterproof.

Yes. The potentiometer allows you to reduce the output voltage within the CC range of 24-48V and proportionally adjust the current. This is useful when your 48V LED fixture or strip installation draws well under 240W, letting you set a more appropriate drive point.

Divide 240W by your strip's wattage per meter. For example, a strip rated at 12W/m allows 20 meters (240W / 12W per meter = 20m). A denser strip at 24W/m allows 10 meters. Always check your strip's rated power per meter and keep the total load at or below 240W for stable operation.

Yes. IP65 means the unit is dust-tight and protected against low-pressure water jets from all directions. It is well suited for weatherproof outdoor enclosures, junction boxes, and control cabinets. For direct exposure to heavy rain without an enclosure, or for locations with flooding risk, the IP67-rated HLG-240H-48 provides stronger water protection.
