External/Internal LED Drivers
(198 results)LED drivers provide a constant current, constant voltage, or a combination of both to provide a steady flow of power to residential or commercial LED lighting elements. Topologies include AC to AC, AC to DC, boost, buck, and buck-boost. Because they can accept a wide range of input voltage, LED drivers are selected by choosing the minimum and maximum input voltage, the output voltage and current (max), the overall power output, and dimming features.
