Can the NPF-40-36 be used in outdoor or damp environments?

Yes. The NPF-40-36 is IP67 rated and operates from -40°C to +85°C. Its 150.0 × 53.0 × 35.0 mm sealed case allows installation in outdoor low-power fixtures, humid agricultural settings, and damp industrial enclosures without supplemental weatherproof housing.

What 36V LED applications is the NPF-40-36 designed for?

The NPF-40-36 provides 36V DC at 1.12A (40.32W) in constant-current mode with a CC range of 21–36V. It suits compact 36V LED modules in small architectural fixtures, point-of-sale display lighting, and automation equipment incorporating 36V LED strings where a low-wattage constant-current source is needed.

How does the NPF-40-36 compare to the NPF-40-42?

Both share IP67, the 150.0 × 53.0 × 35.0 mm housing, and 0.49 kg weight. NPF-40-36 outputs 36V at 1.12A (40.32W, CC range 21–36V); NPF-40-42 outputs 42V at 0.96A (40.32W, CC range 25–42V). The only difference is the output voltage and corresponding current; select the model matching your LED module's rated voltage.

What is the actual rated output power of the NPF-40-36?

The NPF-40-36 is rated at 40.32W — slightly above 40W — because 36V × 1.12A = 40.32W. This is the maximum continuous output under normal operating conditions.
