LED Drivers serve as an interface between the power supply (line) and the LED (load), converting incoming 50 Hz or 60 Hz AC line power at voltages between 85 to 265 Volts to the regulated DC output current. . Within a set design range, an LED driver circuit should be immune to voltage spikes and other AC line noise. It can filter out harmonics in the output current to keep them from impairing the LED light source’s output quality. IP67 Waterproof LED drivers can be used in wet and rainy environments.
