Keystone’s SmartCurrent LED Drivers provide maximum flexibility

Keystone’s programmable SmartCurrent LED drivers feature multiple wattage options, from 12W to 100W. To set output current, simply program via our user-friendly software to adjust the parameters and meet your application needs.

SmartCurrent features a dim-to-off mode, enabling dimming to 1%, for precise tuning of output current. The drivers also feature a 12Vdc/ 200mA max auxiliary power output.

Program your driver quickly and easily.

Programming your SmartCurrent driver is easy with the SmartCurrent cradle and SmartCurrent software. Download the software to your Windows laptop or PC, place the driver in the cradle, connect it to the SmartCurrent PC software via the included USB cable, then use the software to program the LED driver to the specifications that best suit your needs. The process is fast, simple, and reliable.
