LED Constant current drivers offer a large range of products and also have builtin protection that is required for LED products the constant current LED driver offers stability to LED units preventing harmful current fluctuations from the power source to the LED. While LED constant current drivers come in a variety of models, depending on the voltage and the output of the LED, they have one thing in common. They supply a constant current of regulated power to the LED. All LEDs are sensitive to current fluctuations, and without this constant current, LEDs can experience shortened life spans and malfunctions, ranging from dimming to outright failure. Whether an LED constant current driver requires an ac phase cut dimming or DALI dimming, Meanwell constant current LED drivers have a variety of solutions.
