Frequently Asked Questions
Can I use the LPF-25D-48 with a 48V constant-current LED fixture?
Yes, if the fixture is rated for constant-current operation at 0.53A and works within the 26-48V constant-current range. This model delivers up to 25.44W at 48V, so the connected load needs to stay within that power limit.
Is this driver suitable for sealed outdoor lighting applications?
It can be suitable for sealed outdoor lighting when the LED load requires 0.53A constant current and operates from 26V to 48V. The IP67 waterproof rating supports wet-location use, and the driver provides up to 25.44W.
Can this power supply be used for dimmable display or accent lighting?
Yes, for display or accent lighting products that are designed for constant-current input at 0.53A and a 26-48V operating range. The driver includes built-in 3 in 1 dimming and has a maximum output of 25.44W.
How do I calculate the maximum LED strip length for the LPF-25D-48?
Use this formula: 25.44W divided by the strip's rated watts per meter equals the maximum length. The driver can supply 25.44W total at 48V and 0.53A, but check your strip rated power per meter and confirm it is a constant-current 48V load within the 26-48V range.
Is the LPF-25D-48 okay for wet environments?
Yes, it is rated IP67 waterproof for wet and outdoor locations. It is also specified for operating temperatures from -35°C to +70°C, so the environment should remain inside that range.
