Light Emitting Diodes (LEDs) are the future of lighting and Keystone's LED drivers will take you there today. Keystone's state-of-the-art LED drivers are being used today in tens of thousands of quality installations. From low to high wattage, constant current and constant voltage, fixed output and dimming, as well as many other available features, Keystone has the drivers available to meet your application requirements.

Whether you are in need of a Constant Current LED Driver or a Constant Voltage LED Driver, there are a few basic factors to consider before choosing. If your driver will be connected directly to the load (that is, it will be used to power the LED load directly), you will want to be certain that your Drive Current required by the LEDs matches the Rated Output Current of the Constant Current driver. Also, make sure the Maximum Forward Voltage required of all the LEDs in the array does not exceed the Maximum Output Voltage of the LED driver. Lastly, decide on what type of Dimming is needed, if any, the required Input Voltage and the required Power Factor. Once those factors are determined, we can help you select the correct LED Driver for you applications.
