What dimming methods does the NPF-40D-42 support?

The NPF-40D-42 features built-in 3-in-1 dimming accepting PWM signal, 1–10V analog, and resistance (potentiometer) control. All three interfaces are integrated into the driver, covering the most common lighting control protocols used in commercial and industrial projects.

Is the NPF-40D-42 rated for outdoor or wet installations?

Yes. The NPF-40D-42 is IP67 rated and operates from -40°C to +85°C. Its 150.0 × 53.0 × 35.0 mm sealed plastic housing can be installed directly inside compact outdoor luminaires and damp industrial enclosures.

What LED applications suit the NPF-40D-42's 42V dimmable output at 40W?

The NPF-40D-42 supplies 42V DC at 0.96A (40.32W) in constant-current mode (CC range 25–42V) with 3-in-1 dimming. It suits compact dimmable 42V LED modules in small outdoor accent fixtures, display or shelf lighting with 1–10V controllers, and low-power 42V industrial work lights requiring brightness control.

How does the NPF-40D-42 compare to the NPF-40D-36 and NPF-40D-48?

All three share IP67, 3-in-1 dimming, the 150.0 × 53.0 × 35.0 mm housing, and 0.49 kg weight. NPF-40D-36 is 36V/1.12A (40.32W, CC 21–36V); NPF-40D-42 is 42V/0.96A (40.32W, CC 25–42V); NPF-40D-48 is 48V/0.84A (40.32W, CC 28–48V). Select based on your LED string's rated voltage.
