Information about MEAN WELL PWM-90-12
The MEAN WELL PWM‑90‑12 is a 90 W constant voltage LED driver with PWM output that maintains very uniform LED strip brightness over the full dimming range. With its wide 90–305 V AC input, high efficiency, IP67 encapsulation and defined T‑case range from −40 °C to +85 °C, it is designed for durable, fanless operation in indoor and protected outdoor installations. Thanks to 3‑in‑1 dimming (0–10 V, PWM, resistance), active PFC, low standby consumption and long service life, the PWM‑90‑12 is well suited for professional LED strip, decorative, architectural and industrial lighting projects that require precise brightness control and 24/7 operation.
