Frequently Asked Questions
What dimming signals are supported by the NPF-90D-42?
The NPF-90D-42 has built-in 3-in-1 dimming that accepts PWM signal, 0–10V analog, and resistance control, all natively integrated without external dimming accessories.
Can the NPF-90D-42 power dimmable 42V LED fixtures in outdoor architectural lighting of a commercial building facade?
The NPF-90D-42 delivers 90.3W at 42V with a constant current of 2.15A and a CC voltage range of 25–42V, making it appropriate for 42V LED facade lighting modules where dimming for evening scenes or energy management is needed. Its IP67 rating supports direct outdoor mounting.
How does the NPF-90D-42 compare to the NPF-90D-36 and NPF-90D-48?
All three are 90W dimmable IP67 drivers with 3-in-1 dimming and the same 171.0 × 63.0 × 37.5 mm form factor, differing in output voltage: NPF-90D-36 is 36V at 2.5A (CC range 21–36V), NPF-90D-42 is 42V at 2.15A (CC range 25–42V), and NPF-90D-48 is 48V at 1.88A (CC range 28–48V).
Is the NPF-90D-42 appropriate for outdoor use in high-rainfall regions?
Yes. The NPF-90D-42 is IP67-rated for full dust protection and resistance to temporary water immersion, and its -40°C to +85°C operating range covers humid, high-rainfall outdoor environments.
Does the NPF-90D-42 require an earth ground connection?
No. The NPF-90D-42 is a Class II device with a fully isolated plastic case and no functional ground (FG) terminal, so protective earth grounding is not required.
