Can the NPF-90-42 be installed outdoors without an additional housing?

Yes. The NPF-90-42 carries an IP67 waterproof rating, protecting it against dust and temporary water immersion, and operates from -40°C to +85°C. These specifications support direct outdoor installation without a secondary enclosure.

What LED lighting applications suit the NPF-90-42?

The NPF-90-42 delivers 90.3W at 42V with a constant current of 2.15A and a CC voltage range of 25–42V. It is well matched to 42V constant-current LED modules used in high-pole area lighting, outdoor sports field fixtures, or large industrial bay lights where the LED string voltage falls within 25–42V.

How does the NPF-90-42 compare to the NPF-60-42 and NPF-40-42?

At 42V, the NPF series offers: NPF-40-42 at 40.32W and 0.96A, NPF-60-42 at 60.06W and 1.43A, and NPF-90-42 at 90.3W and 2.15A. The NPF-90-42 also has a larger footprint (171.0 × 63.0 × 37.5 mm, 0.77 kg) versus the smaller 40W and 60W models.

Does the NPF-90-42 include dimming capability?

No. The NPF-90-42 is a fixed constant-current output driver. The NPF-90D-42 offers identical electrical specs (90.3W, 42V, 2.15A, IP67) with built-in 3-in-1 dimming.

What is the CC voltage range of the NPF-90-42?

The NPF-90-42 maintains its 2.15A constant current output for LED loads with a forward voltage between 25V and 42V. Loads outside this window will exit the CC regulation zone.
