Is the NPF-40-24 rated for outdoor or wet-location use?

Yes. The NPF-40-24 is IP67 rated and operates from -40°C to +85°C. It can be installed inside outdoor landscape lights, damp ceiling voids, and humid industrial enclosures without a secondary waterproof housing.

What 24V LED applications work with the NPF-40-24's 40W output?

The NPF-40-24 delivers 24V DC at 1.67A (40.08W) in constant-current mode with a CC range of 14–24V. It suits compact 24V LED systems such as short strip runs for accent or undercabinet lighting, small retail display modules, and low-power 24V embedded indicator lighting in control panels.

How does the NPF-40-24 compare to the NPF-40D-24?

Both output 24V at 1.67A (40.08W) with IP67, the same 150.0 × 53.0 × 35.0 mm housing, and 0.49 kg weight. The NPF-40D-24 adds built-in 3-in-1 dimming (PWM, 1–10V, resistance); the NPF-40-24 provides a fixed constant-current output with no dimming input. Choose the NPF-40D-24 when brightness control is required.

What is the CC voltage range of the NPF-40-24?

The NPF-40-24 regulates output current at 1.67A for any load voltage between 14V and 24V. Below 14V the driver exits CC mode; above 24V is beyond the rated output. This range is important for confirming compatibility with the forward voltage of your LED string at operating temperature.
