◼ Dimming
The Dimmer control may be operated from a potentiometer, an input signal of 0 – 10 Vdc or a PWM signal.
Notes:
1. If the dimming function is not used, please open the yellow, purple and grey.
2. Io is actually output current and Ir is rated current without dimming.
3. Do not connect the dimming return to the output; otherwise the driver will not work normally.
