Mean Well PWM-90-24 is a 90W (max.) 24vdc constant voltage (CV) LED driver with Pulse-Width Modulation (PWM) output. Featuring 3-in-1 dimming controlled via 0-10V, PWM signal or resistance, which produces a linear relationship between the control input and the duty-cycle output current %. Built-in active PFC function and fully isolated plastic housing with an IP67 rating. Features include overload, over-voltage, over-temperature, and short-circuit protection.
