Frequently Asked Questions

Can the HLN-40H-48B be used for 48V sign or channel-letter lighting?

Yes, it is suitable for 48V constant-current sign lighting loads within the 28-48V CC range. It provides up to 0.84A and 40.3W, and the listed features specifically mention signage applications.

Is this driver a fit for 48V accent or display lighting?

It can be used for 48V constant-current accent or display lighting fixtures that require up to 0.84A. The load also needs to stay within the driver's 28-48V constant-current range and 40.3W maximum output.

Can I use the HLN-40H-48B with a 48V constant-current LED strip?

Yes, if the strip is a 48V constant-current type designed for 0.84A operation. This driver is not a general constant-voltage supply, so the strip must match the 28-48V range and constant-current output.

Will the HLN-40H-48B hold up in damp or dusty locations?

The IP64 enclosure is intended for protection against dust and splashing water, which makes it suitable for many damp and sheltered outdoor environments. It is also rated for operation from -40°C to +50°C.

How much 48V LED strip wattage can this driver support?

The maximum available output is 40.3W. To estimate strip length, divide 40.3W by your strip's rated watts per meter, and verify the strip is a 48V constant-current product compatible with 0.84A and the 28-48V CC range.

How does the HLN-40H-48B compare with the other high-voltage HLN-40H options?

Among the higher-voltage HLN-40H models, 36V is rated at 1.12A, 42V at 0.96A, 48V at 0.84A, and 54V at 0.75A, all around 40W output. The HLN-40H-48B is the 48V dimmable version with 40.3W maximum power.
