If the dimming function is not used, the dimming leads should be floated. 2. Io is actual output current and Ir is rated current without dimming control. 3. For the driver to operate properly, the load voltage must be maintained above the minimum voltage threshold (approx. 50% of the max. output voltage for any given 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 output current varying from 100% down to practically 10%. 5. The dimming signal is allowed to be less than 1V, however, when 0-1V, the output current can maintain about 10%Ir. When 8.5-10V, the output current can maintain about 100%Ir. 6. Do not connect the GND of dimming to the output; otherwise the LED driver will not function properly. Parameters Minimum Typical Maximum 10V output voltage 9.8 V 10 V 10.2 V 10V output source current 0 mA — 10 mA Absolute maximum voltage on the 0-10V input pin -2 V — 12 V Source current on 0-10V input pin 0 uA — 0.5 mA Value of Rin (the resistor inside the LED driver which is located between the 1-10V input pin and the 10V output pin) 19.8K 20K 20.2K The dimmer control is operated from either a potentiometer or from an input signal of 1 – 10 Vdc.
