What dimming inputs are available on the NPF-40D-15?

The NPF-40D-15 features built-in 3-in-1 dimming supporting PWM signal, 1–10V analog, and resistance (potentiometer) control. All three interfaces are natively supported, making it compatible with a wide range of commercial dimming panels and controllers.

Is the NPF-40D-15 suitable for wet or outdoor environments?

Yes. The NPF-40D-15 is IP67 rated and operates from -40°C to +85°C. Its 150.0 × 53.0 × 35.0 mm sealed housing can be mounted directly inside outdoor compact fixtures, landscape lighting channels, and damp industrial enclosures.

What 15V LED applications suit the NPF-40D-15's dimmable output?

The NPF-40D-15 provides 15V DC at 2.67A (40.08W) in constant-current mode (CC range 9–15V) with 3-in-1 dimming. It suits dimmable 15V LED modules in small hospitality or retail accent fixtures, display cabinets with 1–10V brightness control, and compact architectural installations requiring smooth dimming.

How does the NPF-40D-15 compare to the NPF-40D-12 and NPF-40D-20?

All three share IP67, 3-in-1 dimming, the 150.0 × 53.0 × 35.0 mm housing, and 0.49 kg weight. NPF-40D-12 is 12V/3.34A (40.08W, CC 7–12V); NPF-40D-15 is 15V/2.67A (40.08W, CC 9–15V); NPF-40D-20 is 20V/2A (40W, CC 12–20V). Select the voltage matching your LED module's rating.
