Frequently Asked Questions
Can I use the LPF-40D-12 for 12V LED strip lighting?
Yes, if the strip is a 12V constant-current load that operates within this driver’s 7-12V constant-current range. The LPF-40D-12 delivers up to 40.08W at 12V and 3.34A, and it includes built-in 3 in 1 dimming.
Is the LPF-40D-12 suitable for dimmable 12V display or signage lighting?
It can be used for 12V constant-current signage or display lighting loads that stay within 3.34A and 40.08W. This model also has built-in 3 in 1 dimming, which makes it suitable when dimming is required from the driver side.
Can this driver be used for 12V wet-location accent lighting?
Yes, for 12V constant-current accent lighting loads within its 7-12V range. The IP67 Waterproof rating supports use in wet or outdoor environments, and the operating temperature range is -40°C to +80°C.
How much 12V LED strip can the LPF-40D-12 support?
Use the driver’s 40.08W maximum output as the limit. Estimated strip length = 40.08W divided by your strip’s rated watts per meter, so check your strip rated power per meter before sizing the run.
Is the LPF-40D-12 waterproof enough for outdoor use?
Yes, it is rated IP67 Waterproof for wet or outdoor locations where that enclosure level is needed. The unit is also specified for operation from -40°C to +80°C.
How does the LPF-40D-12 compare with other dimmable 12V LPF models?
The dimmable 12V LPF siblings are LPF-16D-12 at 16.08W and 1.34A, LPF-25D-12 at 25.2W and 2.1A, LPF-40D-12 at 40.08W and 3.34A, and LPF-60D-12 at 60W and 5A. Compared with the non-dimmable LPF-40-12, this model keeps the same 40.08W, 12V, and 3.34A rating but adds built-in 3 in 1 dimming.
