Mean Well, 20V Output, 40W Output, 2A Output, Constant Voltage

The Mean Well NPF-40-D Series is a range of 40W dimmable LED Drivers with a high efficiency of up to 90% and a low no load power consumption below 0.15W. These LED power supplies are waterproof, with the case made of 94V-0 flame retardant plastic. The interior of the NPF-40-D is fully potted in silicone, making these LED drivers suited to meet the anti-vibration demand up to 5G and enhancing the heat dissipation. The NPF-40D features a built-in 3 in 1 dimming function 01 to 10Vdc, PWM signal or resistance. These Mean Well LED drivers are IP67 rated and can be used in highly dusty and humid harsh environment. The class II design and the double insulation weather resistant cable makes the NPF-40-D Led drivers ideal for flexible installation of various types of lighting systems.
