Frequently Asked Questions
Can I use the LPF-90-42 for 42V LED signage or display lighting?
It can be used for 42V LED signage or display lighting when the load matches the 42V output and stays within 90.3W total. This is a constant current driver with a 25-42V range, so the connected lighting load needs to fall inside that range.
Is the LPF-90-42 a fit for 42V linear lighting fixtures?
Yes, it is suited to 42V linear lighting fixtures that need up to 2.15A and no more than 90.3W. The fixture should be designed to operate within the driver's 25-42V constant current range.
Can the LPF-90-42 be used for outdoor decorative or facade lighting?
Yes, this model is often considered for outdoor decorative or facade lighting because it is IP67 waterproof and rated for -40°C to +70°C operation. The lighting load still needs to match the 42V output class and remain within 90.3W.
How do I estimate LED strip length for the LPF-90-42?
Use the driver's maximum power: 90.3W. The length calculation is 90.3W divided by your strip's watts per meter, so maximum length = 90.3W / rated W per meter. Check your strip rated power per meter before sizing the run.
Is the LPF-90-42 suitable for wet or exposed environments?
The LPF-90-42 carries an IP67 waterproof rating and operates from -40°C to +70°C. That makes it appropriate for wet or exposed locations when those environmental limits fit the project.
What are the main output differences between LPF-90-42 and the other LPF-90 models?
The non-dimming LPF-90 family includes 15V at 75W and 5A, 20V at 90W and 4.5A, 24V at 90W and 3.75A, 30V at 90W and 3A, 36V at 90W and 2.5A, 42V at 90.3W and 2.15A, 48V at 90.24W and 1.88A, and 54V at 90.18W and 1.67A. The LPF-90D family keeps the same output classes and adds built-in dimming.
