Frequently Asked Questions
Can the NPF-40-20 be installed in damp or outdoor locations?
Yes. The NPF-40-20 is IP67 rated and operates from -40°C to +85°C. Its 150.0 × 53.0 × 35.0 mm sealed plastic housing allows direct mounting inside outdoor fixtures and wet industrial enclosures without additional waterproofing.
What LED applications suit the NPF-40-20's 20V 40W output?
The NPF-40-20 supplies 20V DC at 2A (40W) in constant-current mode with a CC range of 12–20V. It is appropriate for low-power 20V LED systems including compact architectural accent lights, small signage modules, and embedded lighting in automated equipment that operates at 20V.
How does the NPF-40-20 compare to the NPF-40-24?
Both are in the ~40W class with IP67, the same 150.0 × 53.0 × 35.0 mm housing, and 0.49 kg weight. NPF-40-20 outputs 20V at 2A (40W, CC range 12–20V); NPF-40-24 outputs 24V at 1.67A (40.08W, CC range 14–24V). The distinction is the output voltage; select the model that matches your LED module.
What certifications does the NPF-40-20 hold?
The NPF-40-20 is certified to CB, CCC, CE, EAC, ENEC, and UL. These cover North America (UL), Europe (CE, ENEC), Russia/Eurasia (EAC), and China (CCC), making it suitable for multi-region commercial deployments without separate approval processes.
