Frequently Asked Questions
Is the NPF-40-15 suitable for installation in damp or outdoor environments?
Yes. The NPF-40-15 is IP67 rated and operates from -40°C to +85°C. Its compact sealed housing can be placed inside outdoor low-voltage lighting fixtures, horticultural enclosures, or damp industrial cabinets without additional waterproofing.
What types of 15V LED systems match the NPF-40-15?
The NPF-40-15 provides 15V DC at 2.67A (40.08W) in constant-current mode with a CC range of 9–15V. It suits low-power 15V LED modules in small signage, accent lighting, embedded automotive-format displays, and sensors that require a 15V constant-current source of around 40W.
How does the NPF-40-15 compare to the NPF-40-12 and NPF-40-20?
All three are in the ~40W family with IP67, the same 150.0 × 53.0 × 35.0 mm housing, and 0.49 kg weight. NPF-40-12 outputs 12V/3.34A (40.08W, CC 7–12V); NPF-40-15 outputs 15V/2.67A (40.08W, CC 9–15V); NPF-40-20 outputs 20V/2A (40W, CC 12–20V). Choose the voltage that matches your LED load's rated voltage.
Does the NPF-40-15 require a protective earth connection?
No. The NPF-40-15 is a Class II device with a fully isolated plastic case and no FG terminal. Double insulation eliminates the need for a chassis ground, which is useful in compact plastic luminaire housings where grounding is impractical.
