Mean Well 40W Dimmable Constant Voltage LED Drivers - PWM-40 Series The Mean Well PWM-40 Series is a range of 40W LED Drivers with a built-in 3 in 1 dimming function and transmitting PWM style output, adapting to all kinds of LED strips and ensuring that colour temperature and brightness is maintained consistent. The PWM-40 LED drivers have a high efficiency of up to 90% and a low no load power consumption below 0. 5W. These LED power supplies are waterproof, with the case made of 94V-0 flame retardant plastic. The interior of the PWM-40 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 PWM-40 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 PWM-40 Led drivers ideal for flexible installation in applications like LED strip lighting, indoor LED lighting, LED decorative lighting and LED architecture lighting.
