MEAN WELL PWM-90-48 – 90W Dimmable LED Driver, 48V DC, 1.88A, IP67, 3-in-1 Dimming
The MEAN WELL PWM-90-48 is a high-efficiency 90W AC/DC LED power supply designed to deliver reliable 48V DC power for professional LED lighting applications. Featuring constant voltage PWM output, integrated 3-in-1 dimming technology and active Power Factor Correction (PFC), it provides precise brightness control and energy-efficient operation for residential, commercial and architectural lighting installations.
The driver delivers a rated output voltage of 48V DC with a maximum current of 1.88A and an output power of 90.24W. Its PWM output technology allows smooth brightness adjustment while maintaining a constant output voltage level, making it particularly suitable for compatible LED strips, decorative lighting and other constant-voltage LED systems.
The integrated 3-in-1 dimming function supports 0–10V DC, 10V PWM signals and resistance-based control. With a dimming range of 0–100%, users can adjust lighting intensity according to different environments and requirements.
With a typical efficiency of 90.5%, the PWM-90-48 minimizes energy losses while maintaining reliable performance. Its fully encapsulated IP67-rated enclosure provides protection against dust and water ingress, making it suitable for demanding indoor and outdoor lighting installations.
The fanless design ensures quiet operation, while built-in electrical protection features enhance reliability and operational safety.
