Frequently Asked Questions
Can I use the HLN-40H-54B for dimmable LED signage?
Yes, if the sign uses a constant-current LED load that operates within 32-54V at 0.75A. This model is rated 40.5W at 54V and is listed as suitable for signage applications. The load still has to match the driver's constant-current electrical range.
Is the HLN-40H-54B suitable for a 54V LED lighting fixture that needs dimming?
It can be, as long as the fixture is a constant-current design within the 32-54V CC range and draws 0.75A. The available output power is 40.5W, so the fixture must stay inside that limit. This is a better fit for fixtures specified around 54V constant current than for constant-voltage products.
How much 54V LED strip can this driver support?
Use the power rating to estimate length: 40.5W divided by your strip's rated watts per meter equals the maximum run length. That estimate only applies if the strip is a 54V constant-current product that fits the 32-54V, 0.75A output range. Check your strip rated power per meter before sizing.
Can the HLN-40H-54B be used in outdoor or wet locations?
It is designed for environments where IP64 protection is appropriate, with an operating temperature range of -40°C to +50°C. IP64 supports resistance to dust and splashing water, but it does not mean submersible service. Use it where the site conditions match an IP64 driver.
What is the difference between the HLN-40H-54A and HLN-40H-54B, and what other HLN options exist?
The HLN-40H-54A and HLN-40H-54B share the same 40.5W, 54V, 0.75A electrical rating. In the 40H family, the listed outputs are 12V 3.33A, 15V 2.67A, 20V 2A, 24V 1.67A, 30V 1.34A, 36V 1.12A, 42V 0.96A, 48V 0.84A, and 54V 0.75A. Higher-output siblings listed here include 60H models from 15V 4A through 54V 1.15A and 80H models from 12V 5A through 54V 1.5A.
