Can I use the LPF-40-48 for a 48V LED sign or display light?

Yes, if the lighting load is a 48V constant-current type and operates within the 28-48V constant-current range. The LPF-40-48 delivers up to 40.32W at 48V and 0.84A.

Is the LPF-40-48 suitable for 48V architectural lighting?

It can be used for 48V constant-current architectural lighting loads that stay within 0.84A and 40.32W. The IP67 waterproof enclosure also supports use in more exposed lighting environments.

Can this driver run a 48V LED strip for accent or cove lighting?

It can only run a strip that is specifically designed for 48V constant-current operation. This driver is limited to 40.32W total output and 0.84A, so the strip load must match those figures.

How do I calculate the maximum 48V strip length for the LPF-40-48?

Use the driver’s 40.32W maximum output as the limit. Estimated strip length = 40.32W divided by your strip’s rated watts per meter, so check your strip rated power per meter before sizing it.

Is the LPF-40-48 appropriate for outdoor lighting projects?

Yes, it has an IP67 Waterproof rating for wet or outdoor use. It is also specified for operation from -40°C to +80°C.

How does the LPF-40-48 compare with the other 48V LPF models?

At 48V, the series includes LPF-16-48 at 16.32W and 0.34A, LPF-25-48 at 25.44W and 0.53A, LPF-40-48 at 40.32W and 0.84A, LPF-60-48 at 60W and 1.25A, and LPF-90-48 at 90.24W and 1.88A. Dimmable versions are LPF-16D-48, LPF-25D-48, LPF-40D-48, LPF-60D-48, and LPF-90D-48 with the same listed voltage and output ratings.
