Information about MEAN WELL PWM-90-48

The MEAN WELL PWM‑90‑48 is a 90 W constant voltage LED driver with PWM output that provides a stable 48 V DC for high‑power LED strips and modules, ensuring very uniform brightness across the entire dimming range. With its wide 90–305 V AC input range, high efficiency around 90,5%, IP67 potted housing and case temperature capability from −40 °C to +85 °C, it is suitable for demanding, fanless installations in indoor and protected outdoor environments. The 3‑in‑1 dimming interface (0–10 V, PWM, resistance), optional DALI/DALI‑2 control, active PFC and long service life make the PWM‑90‑48 particularly well suited for professional 48‑V LED strip, architectural, decorative and industrial lighting systems that require precise dimming and reliable 24/7 operation.
