If the dimming function is not used, leave the dimming leads unconnected (floating). 2. Io is the actual output current and Ir is the rated current without dimming control. 3. For the driver to operate properly, the load voltage must be maintained above the minimum voltage threshold (~50% of the maximum output voltage for the specific model). 4. If the output voltage is maintained above 50% of the maximum output voltage, the dimming control may be operated over the entire 1-10V range with the output current varying from 100% down to ~10% of nominal. 5. The dimming signal may be <1V, but if this voltage is <1V, the output current can only maintain ~10% Ir. When the signal voltage is ~8.5-10V, the output current can maintain ~100% Ir. 6. Do not connect the GND of the dimming leads to output. The driver will not function normally if it is. Data Sheet © 2012 SL Power Electronics Corp.
