Choice of power supply
Since this led-unit is current driven, the voltage that the power supply has to
deliver, is depending on the number of units that are connected in series.
The voltage drop per led-unit is approximately 3 volt. So in case of 12 units,
the current in the circuit will be 350 mA, and the voltage drop over the
complete circuit will be:
12 led-units x 3 volt per unit = 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) x 36 (volt) = 12,6 watt.
We specify these power supplies, depending on the number of units
connected in series.

LEDINTA 350C210 DHO also has a 1-10 volt dim-input. If your setup needs no dimming, it
can stay unconnected.
Manuals of the led-drivers are supplied with your setup.
