DIMMING CONTROL
The dimmer control may be operated from either a potentiometer or from an input
signal of 1 – 10 Vdc. Two recommended implementations are provided below.

Notes:
1. Io is actual output current and Ir is rated current.
2. If the dimming function is not used, please short 10 V output pin (yellow) and 1-10 V input pin(purple).
The output current is about 92% Ir when the 1-10V input pin is oating.
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. The dimming voltage can be tuned down to less than 1V, and the output current will be decreased to about
10% Ir; but the connected LEDs may icker. Keeping dimming voltage greater than 1V is strongly recommended.
5. Do not connect the GND of dimming to the output; otherwise, the LED driver will not work normally.
