What dimming protocols are supported by the NPF-120D-48?

The NPF-120D-48 includes built-in 3-in-1 dimming, accepting PWM signal, 1–10V analog, and resistance (potentiometer) inputs. These cover the most common lighting control interfaces used in commercial building management systems and outdoor lighting controllers.

Can the NPF-120D-48 be used in outdoor or damp environments?

Yes. The NPF-120D-48 is rated IP67 for dust and temporary submersion protection and operates from -40°C to +90°C. It is suitable for direct installation inside outdoor luminaires, landscape lighting fixtures, and harsh industrial enclosures.

What 48V LED systems benefit from the NPF-120D-48's dimmable output?

The NPF-120D-48 provides 48V DC at 2.5A (120W) in constant-current mode with a CC range of 28–48V. It suits dimmable 48V LED high-bay fixtures, outdoor area lights, tunnel lighting, and industrial work-lighting systems where remote brightness control via 1–10V or PWM is specified.

How does the NPF-120D-48 compare to the NPF-120D-54?

Both have IP67, 3-in-1 dimming, the same 191.0 × 63.0 × 37.5 mm dimensions, and 0.97 kg weight. NPF-120D-48 outputs 48V at 2.5A (120W, CC range 28–48V); NPF-120D-54 outputs 54V at 2.3A (124.2W, CC range 32–54V). The choice depends on whether your LED string requires a 48V or 54V constant-current source.
