Frequently Asked Questions
What dimming interfaces does the NPF-120D-54 support?
The NPF-120D-54 has built-in 3-in-1 dimming, accepting PWM signal, 1–10V analog, and resistance (potentiometer) control. All three are available on the same driver without any external interface module, making it compatible with most commercial and industrial lighting control systems.
Is the NPF-120D-54 rated for outdoor installation?
Yes. The NPF-120D-54 is IP67 rated and operates from -40°C to +90°C. These ratings support direct mounting inside outdoor street lights, facade fixtures, and industrial luminaires exposed to rain, humidity, or extreme temperatures.
What LED applications suit the NPF-120D-54's 54V dimmable output?
The NPF-120D-54 outputs 54V DC at 2.3A (124.2W) in constant-current mode with a CC range of 32–54V. It suits dimmable 54V LED modules in commercial street lighting, sports arena area lights, and large-format industrial high-bay fixtures where central brightness control is required.
How does the NPF-120D-54 compare to the non-dimmable NPF-120-54?
Both output 54V at 2.3A (124.2W) with IP67 protection, identical 191.0 × 63.0 × 37.5 mm housing, and 0.97 kg weight. The NPF-120D-54 adds 3-in-1 dimming (PWM, 1–10V, resistance) not present on the NPF-120-54. For fixed-output 54V applications, the NPF-120-54 is the straightforward option; use the NPF-120D-54 when dimming control is required.
