Frequently Asked Questions
What dimming methods does the NPF-120D-42 support?
The NPF-120D-42 has built-in 3-in-1 dimming that accepts PWM signal, 1–10V analog voltage, and resistance (potentiometer) control. All three interfaces are built into the same driver, eliminating the need for external dimming adapters.
Is the NPF-120D-42 suitable for installation in exposed outdoor fixtures?
Yes. The NPF-120D-42 is IP67 rated for dust-tight and temporary immersion resistance, and its operating range spans -40°C to +90°C. These ratings make it appropriate for outdoor luminaires, roadway lighting enclosures, and industrial installations with high ambient temperatures or moisture exposure.
What types of 42V LED lighting systems use the NPF-120D-42?
The NPF-120D-42 delivers 42V DC at 2.9A (121.8W) in constant-current mode with a CC range of 25–42V. It suits dimmable 42V LED street lights, outdoor floodlights, and commercial high-bay fixtures where 1–10V or PWM dimming control from a central panel is required.
How does the NPF-120D-42 compare to the NPF-120D-36 and NPF-120D-48?
All three share IP67 protection, 3-in-1 dimming, and the 191.0 × 63.0 × 37.5 mm housing (0.97 kg). NPF-120D-36 is 36V/3.4A at 122.4W (CC 21–36V); NPF-120D-42 is 42V/2.9A at 121.8W (CC 25–42V); NPF-120D-48 is 48V/2.5A at 120W (CC 28–48V). Select the voltage that matches your LED module's rating.
