Frequently Asked Questions
Can I use the HLN-40H-48A for 48V LED signage?
Yes, it can be used for 48V constant-current signage loads that operate within the 28-48V CC range. It supplies up to 0.84A with a maximum output of 40.3W, and the product features list signage applications.
Is this driver suitable for 48V linear lighting fixtures?
It is suitable for 48V constant-current linear lighting fixtures that need up to 0.84A and stay within the 28-48V operating window. The fixture also needs to remain within the driver's 40.3W output limit.
Can the HLN-40H-48A power a 48V LED strip?
Only if the strip is a 48V constant-current LED strip that is designed to run at 0.84A. Because this is a constant-current driver with a 28-48V range, the strip has to match both the current requirement and the voltage range.
Is the HLN-40H-48A okay for outdoor or washdown areas?
It is suitable for dust-exposed and splash-prone locations because the enclosure is rated IP64. That supports many sheltered outdoor uses, but IP64 is for splashing water rather than immersion, and the operating temperature range is -40°C to +50°C.
How do I calculate the maximum 48V LED strip length for this driver?
The driver's maximum output is 40.3W. To estimate length, divide 40.3W by the strip's rated power per meter, and check that the strip is a 48V constant-current product compatible with 0.84A and the 28-48V CC range.
What are the main output differences across the HLN-40H series?
The HLN-40H series spans 12V at 3.33A, 15V at 2.67A, 20V at 2A, 24V at 1.67A, 30V at 1.34A, 36V at 1.12A, 42V at 0.96A, 48V at 0.84A, and 54V at 0.75A. The HLN-40H-48A is the adjustable 48V version with 40.3W maximum output.
