UBA2015AT Reference Design 120 V (AC)
3.1 Dimming without using an external voltage source
The ballast is dimmed with a voltage source of 1 V (DC) to 10 V (DC) connected to
connector X1.
It is also possible to dim with an external logarithmic potentiometer of 470 k (for
example, no external voltage supply is available). The potentiometer must connect to pin
5 (gray wire, DIM) and pin 4 (violet wire, DIM+) of connector X1.
