Can the NPF-90-54 withstand direct outdoor exposure to snow and ice?

Yes. The NPF-90-54 has an IP67 rating for full dust and temporary water immersion protection, and a minimum operating temperature of -40°C. These specifications cover outdoor environments with snow and ice exposure.

What LED applications are suited to the NPF-90-54?

The NPF-90-54 delivers 90.18W at 54V with a constant current of 1.67A and a CC voltage range of 32–54V. It suits high-voltage 54V LED string arrays used in large outdoor signage, high-mast area lighting, or industrial inspection systems where longer LED strings reduce overall current requirements.

How does the NPF-90-54 compare to other 54V models in the NPF series?

At 54V: NPF-40-54 is 41.04W at 0.76A, NPF-60-54 is 60.48W at 1.12A, NPF-90-54 is 90.18W at 1.67A, and NPF-120-54 is 124.2W at 2.3A. All four share IP67 rating and 90–305VAC input; the selection is determined by total LED load wattage.

Does the NPF-90-54 include dimming?

No. The NPF-90-54 is a fixed constant-current driver. If dimming at 54V and 90W is required, the NPF-90D-54 shares identical electrical specs with added built-in 3-in-1 dimming.

What are the physical dimensions of the NPF-90-54?

The NPF-90-54 measures 171.0 × 63.0 × 37.5 mm and weighs 0.77 kg, the standard size for the NPF-90 family regardless of output voltage.
