STEP 8:
At the beginning of the setup, you will have the black loop-back
cable, and a red cable, coming from the first module. These
cables need to be connected to the power supply, delivered
together with your setup.

Choice of power supply
Since this led-unit is current driven, the voltage that the power
supply has to deliver, is dependent on the number of modules
that are connected in series.
The voltage drop over one module is approx 3 volt. So in case of
12 modules, the current in the circuit will be 350 mA, and the
voltage drop over the complete circuit will be:
12 modules x 3 volt(over one module) = 36 volt.
It is important to understand that not all current sources are
capable of producing a current of 350 mA at 36 volt.
In this example, the power generated by the power supply is:
0,350 (A) x36 (volt) = 12,6 watt.
We specify three different power supply’s to use, depending on
the number of units connected in series.

Manuals of the LED drivers are supplied with your setup.
Note that the power supply LEDINTA 350C210 DHO has a 1-10
volt dim-input. When your setup needs no dimming, the wires
can stay unconnected.
