Applications
The NPF-40D-24 is perfectly suited for smaller outdoor and wet-location LED lighting installations including garden and landscape lighting, pathway illumination, deck and patio lighting, architectural accent lighting, signage and display lighting, underwater lighting features, commercial facade illumination, hospitality and restaurant ambient lighting, and residential outdoor LED strip lighting. Its compact size and 3-in-1 dimming make it extremely versatile for creative lighting designs.
Installation Notes
The fully potted design of the NPF-40D-24 means no additional enclosure is needed for outdoor installations. Mount using the integrated mounting points or cable ties. The 3-in-1 dimming interface provides flexibility — select the dimming method that best suits your control system. For 0-10V dimming, use shielded cable and keep dimming wires away from AC lines. For PWM dimming, ensure compatible controller specifications. All cable entry points should be properly sealed for IP67 maintenance. Consult the Mean Well NPF-40D-24 datasheet for complete dimming wiring configurations.
