Frequently Asked Questions
Is the NPF-40-54 suitable for outdoor LED applications?
Yes. The NPF-40-54 is IP67 rated and operates from -40°C to +85°C. Its compact 150.0 × 53.0 × 35.0 mm sealed housing allows direct mounting inside outdoor low-wattage luminaires and damp enclosures without additional weather protection on the driver.
What LED systems suit the NPF-40-54's 54V output?
The NPF-40-54 provides 54V DC at 0.76A (41.04W) in constant-current mode with a CC range of 32–54V. It suits 54V LED modules in compact architectural accent fixtures, small commercial display lighting, and automation equipment with 54V LED strings at low wattage.
How does the NPF-40-54 compare to the NPF-40D-54?
Both output 54V at 0.76A (41.04W) with IP67, the same 150.0 × 53.0 × 35.0 mm housing, and 0.49 kg weight. The NPF-40D-54 adds built-in 3-in-1 dimming (PWM, 1–10V, resistance); the NPF-40-54 has no dimming capability. Use the NPF-40D-54 when brightness adjustment is needed.
What is the rated output power of the NPF-40-54?
The NPF-40-54 is rated at 41.04W — slightly above 40W — because 54V × 0.76A = 41.04W. This is the maximum continuous rated output. The driver accepts 90–305VAC input and carries a 5-year warranty.
