MeanWell Introduces New LED Drivers with Low No Load Power Consumption

Thanks to the market trend of green and environmental protection, there has been an explosive growth of the demand for LED in the lighting industry. Meanwhile, there are always new lighting applications with respect to LED being unveiled, and the worldwide safety or energy regulations for LED luminary continue to be updated. In order to fulfill the market need, MEAN WELL releases the new 90W single output LED power supply with active PFC function~NPF-90, NPF-90D and PWM-90 series.

•    90~305 VAC full range input
•    Built-in active PFC function
•    NPF-90(D): CV+CC design, DC style output
•    PWM-90: CV design, PWM style output
•    Setup time <500 ms
•    High efficiency up to 91%
•    Fanless design, cooling by free air convection
•    -40~+70°C working temperature
•    No load power consumption<0.5 W (<0.15 W for NPF-90)
•    Protections: Short circuit / Overload {PWM-90} or Over current {NPF-90(D)} /
over voltage / over temperature
•    Fully enclosed plastic case (UL 94V-0)
•    IP67 design
•    Class II power unit, no FG
•    Approvals: UL / CUL / ENEC / CB / CE
•    Dimension(LxWxH): 171x 63x 37.5mm
•    5 years warranty

Completely satisfying the global energy saving concern for luminaries, these three series all come with the setup time less than 500 ms, the no load power consumption less than 0.5 W (for NPF-90, it is less than 0.15 W) and the built-in active PFC function. Here is the highlight for each individual series: NPF-90 exploits the “constant voltage (CV)+constant current (CC) mode” design that allows this series to work ideally for the major LED lighting application; NPF-90D further provides the 3 in 1 dimming function that the lighting fixture designers are able to adjust the light intensity via 0~10 VDC, PWM signal, or resistance and realize further energy saving; PWM-90 provides the “constant voltage mode” design and the PWM style output as well as the 2 in 1 dimming function (0~10 VDC or PWM signal) that enables this series to work perfectly with LED strips or the LED luminaries using current limiting resistors and supply the complete dimming function at the same time.

NPF-90, NPF-90D and PWM-90 are all Class II power unit (no FG). The input end accepts the full range 90~305VAC, and the output end supplies the DC voltage that the LED lighting units or strips use the most frequently. These three series all adopt the 94V-0 flame retardant plastic enclosure, and the interior is fully filled with heat conductive silicone; in addition, the working efficiency is high up to 91% that they can operate between -40°C and +70°C under free air convection. The thorough protection functions include short circuit protection, overload or over current protection, over voltage protection, and over temperature protection. NPF-90, NPF-90D and PWM-90 series are certified with the major international regulation standards such as UL8750 and EN61347-1, and the circuit design refers to the safety norm of household electrical appliances, EN60335-1, providing high flexibility for lighting system design. Suitable applications include indoor LED lighting, LED decorative lighting, LED architecture lighting, and etc.
