What dimming protocols does the NPF-120D-20 accept?

The NPF-120D-20 supports 3-in-1 dimming: PWM signal, 1–10V analog voltage, and resistance (potentiometer) control. All three methods are handled by the same built-in interface, so the driver can be paired with common 0–10V dimmers, DALI-to-analog converters, or simple potentiometer circuits.

Can the NPF-120D-20 be installed in outdoor luminaires without additional weatherproofing?

Yes. The NPF-120D-20 is rated IP67, making it resistant to dust and temporary water immersion. Its -40°C to +90°C operating temperature means it can be embedded in outdoor fixtures across a broad range of climates without supplemental enclosure protection on the driver body.

What LED systems match the NPF-120D-20's 20V output?

The NPF-120D-20 delivers 20V DC at 6A (120W) with a CC range of 12–20V. It suits 20V LED modules in dimmable architectural and retail lighting, mid-voltage linear fixtures designed for 20V constant-current drivers, and museum or gallery lighting where precise intensity control via 1–10V is required.

How does the NPF-120D-20 compare to the non-dimmable NPF-120-20?

Both supply 20V at 6A (120W) with IP67, identical dimensions (191.0 × 63.0 × 37.5 mm), and 0.97 kg weight. The NPF-120D-20 adds built-in 3-in-1 dimming (PWM, 1–10V, resistance); the NPF-120-20 provides a fixed output with no dimming capability. For fixed-brightness designs, the NPF-120-20 is the simpler and often lower-cost option.
