The PWM-120-24DA is a 120-watt, 24-volt, 5-amp constant-voltage DALI LED driver manufactured by Mean Well. It is designed to provide efficient power conversion for low-voltage LED lighting systems. It features PFC (power factor correction) as well as active PFC, which reduces total harmonic distortion while ensuring a clean, efficient, and reliable power signal. Additionally, it can be used with DALI systems, allowing both local and remote control of the light output. Other features include short circuit protection, over-voltage protection, over-temperature protection, and built-in surge protection. The PWM-120-24DA is cULus approved and has a 5-year warranty.
