Frequently Asked Questions
What dimming protocols does the NPF-40D-20 accept?
The NPF-40D-20 supports 3-in-1 dimming: PWM signal, 1–10V analog, and resistance (potentiometer) control. These are built into the driver without requiring external adapters.
Is the NPF-40D-20 rated for outdoor or wet-location installations?
Yes. The NPF-40D-20 is IP67 rated and operates from -40°C to +85°C. It can be installed inside outdoor low-wattage fixtures and damp enclosures without supplemental weatherproofing of the driver body.
What LED applications match the NPF-40D-20's dimmable 20V 40W output?
The NPF-40D-20 delivers 20V DC at 2A (40W) in constant-current mode (CC range 12–20V) with 3-in-1 dimming. It suits dimmable 20V LED accent and display lighting with 1–10V scene control, compact retail fixtures, and small architectural installations requiring smooth output adjustment.
How does the NPF-40D-20 compare to the NPF-40D-24?
Both share IP67, 3-in-1 dimming, the 150.0 × 53.0 × 35.0 mm housing, and 0.49 kg weight. NPF-40D-20 outputs 20V at 2A (40W, CC range 12–20V); NPF-40D-24 outputs 24V at 1.67A (40.08W, CC range 14–24V). Select the model whose voltage matches your LED module.
