0-10V Dimming control output
A voltage between 0V and 0.2V on this terminal gives minimum light output (5% of maximum)
A voltage of 10V gives maximum light output. Between 0V and 10V terminal voltage, the light output is
continuously variable.
The negative terminal of the 0-10V and LED negative are not isolated from each other, this means that the
insulation class of the external 0-10V controller may affect the ground isolation and SELV rating of the LED
output.
To maintain SELV isolation of the driver output the 1-10V dimming controller and network should have
reinforced or double insulation from the mains supply.
Setting the desired current
A-Style – For the higher of the two currents the two brown wires must be kept separate, i.e. open circuit. The
end of the wires should be isolated to avoid short circuits. For the lower current the two brown wires should be
shorted together with the connection isolated to avoid short circuits.
B-Style – Drivers are provided set to the highest current of the two supported. In order to set the lower current
the DIP switch should be moved to the alternate position as shown on the label.
