PrevaLED ® Core Z3 LED modules | Electrical considerations
3.7 OT LCTS electronic control gear – LEDset GEN 1
If you want to use PrevaLED ® Core Z3 LED modules with
LCTS control gears, you need to attach a resistor to the
ECG to adjust the needed current.
OT 35/220-240/700 LCTS


3.4 OTi electronic control gear series
If you use the PrevaLED ® Core Z3 series in combination with
the OSRAM OTi control gear series, you will get the best
results and the full functionality of the LED module.
The system includes a one-wire communication interface,
using the LEDset II communication standard between the
control gear and the module. A thermal derating and a fl ux
calibration are included.
Therefore, please connect all three terminals of the module
to the control gear:
3.5 OT FIT electronic control gear series
It is also possible to use the PrevaLED ® Core Z3 series with
a constant-current driver. The OT FIT series offers different
available currents. To wire the module to the ECG, please
connect the ports LED+ and LED- to the module as shown
in the image below. The current is selected by a bridge
between ports 3, 4 and 5:
3.6 OTe electronic control gear series
If you like to use the OSRAM OTe series, please connect the
terminal LED+ to the module and select the desired current
by connecting it to only one of the output terminals 21, 22
or 23.
