40 Watt 12 Volt 3.34 Amp Enclosed LED Power Supply with PFC

12 Volts @ 3.34 Amps, Constant current region: 7.2-12V

The NPF-40 is a 40 watt waterproof single-output LED power supply series. It adopts the universal input range from 90VAC to 305VAC and incorporates built-in PFC function. The enclosure design is a 94V-0 flame retardant plastic case. The interior is fully potted with silicone that enhances the heat dissipation and allows the power supply to meet the anti-vibration demand up to 5G; it also thus conforms to IP67 level, enabling NPF-40 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 0.15W, the NPF-40 can meet the energy saving demand for 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 a temperature range from -40 to +70°C and complies with the relevant global lighting safety certification.
