40 Watt 12 Volt 3.34 Amp Enclosed LED Power Supply with PFC & Dimming
12 Volts @ 3.34 Amps, Constant current region: 7.2-12V
The NPF-40D is a 40 watt waterproof single-output LED power supply series. In addition to the fundamental LED driving function, the NPF-40D is equipped with a built-in 3 in 1 dimming function (0-10VDC, PWM signal or resistance) that simplifies brightness adjustment for system designers to achieve light reduction and energy conservation. The entire series adopts the universal input range from 90-305VAC and incorporates built-in power factor correction (PFC). The enclosure design is a 94V-0 flame retardant plastic case. The interior is full potted with silicone that enhances the heat dissipation and allows the power supply to meet the anti-vibration demand up to 5G; it also conforms to IP67 level enabling the power supply to be used in highly dusty and highly humid harsh environments.
Providing a high efficiency up to 86% and a low no load power consumption below 0.5W, NPF-40D can satisfy the energy saving demand of new generation LED lighting. The class 2 design (without FG pin) and the double insulation weather-resistant cable (SJTW) on the input side make it convenient for users to flexibly install on various types of lighting systems. The entire series can operate within the temperature range of -40 to +70°C and complies with the relevant global lighting safety certification.
