Typ. Max. 10V output voltage 9.8V 10V 10.2V 10V output source current 0mA 10mA Voltage on the 0-10v input pin 500mV 12V Source current on 0-10V input pin 0mA 1mA 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.
