Frequently Asked Questions
Can I use the LPF-40-42 for a 42V LED signage application?
Yes, if the sign uses a 42V constant-current LED load within the driver’s 25-42V constant-current range. The LPF-40-42 provides up to 40.32W at 42V and 0.96A.
Is the LPF-40-42 a good choice for 42V linear lighting fixtures?
It can be used with 42V constant-current linear lighting loads that stay within 0.96A and 40.32W. Its IP67 enclosure also makes it suitable where a waterproof driver is needed.
Can this model power a 42V LED strip for display lighting?
Only if the strip is built for 42V constant-current operation and falls inside the 25-42V range. This driver outputs up to 40.32W and 0.96A, so the strip load must match those limits.
What strip length can I estimate from the LPF-40-42?
The driver’s maximum output power is 40.32W. Estimated strip length = 40.32W divided by your strip’s rated watts per meter, so check your strip rated power per meter before deciding run length.
Can the LPF-40-42 be used outdoors in rain or washdown areas?
This model is rated IP67 Waterproof, so it is intended for wet and outdoor conditions where that level of protection is required. Its operating temperature range is -40°C to +80°C.
What are the 42V alternatives in the LPF series if I need more or less power?
For 42V models in this series, LPF-16-42 is 16.38W at 0.39A, LPF-25-42 is 25.2W at 0.6A, LPF-40-42 is 40.32W at 0.96A, LPF-60-42 is 60.06W at 1.43A, and LPF-90-42 is 90.3W at 2.15A.
