Part # : 133360


Product Description



Keystone’s Smart Current LED Drivers provide maximum flexibility

Simply adjust the parameters of our programmable LED driver to meet your application needs. Smart Current features a dim-to-off mode, enabling dimming to 1%, for precise tuning of output current. Our Smart Current LED drivers also feature a 12Vdc/ 200mA max auxiliary power output.


Program your LED driver quickly and easily according to your lighting needs

Programming the driver is easy with the Smart Current Cradle. The cradle connects the driver to the Smart Current PC software via USB (cable included). Start by downloading the Smart Current PC software then use the software to program the LED driver to the specifications that best suit your needs.
