Dimming Control (on secondary side)

Notes:

1. Io is actual output current and Ir is rated current without dimming control.

2. 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).

3. 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 10% to 100% of Ir.

4. The dimming input signal may be less than 1V; however, no further dimming will occur between 0V and 1V.

5. The internal resistor Rin is 20K, and Vcc is about 15V.

6. Do not connect the GRAY of dimming to the output; otherwise, the LED driver can not work normally.
