OSRAM DIM MCU G2 Control Unit For Manually Dimming Luminaires
Product Information
- The DIM MCU G2 is a control unit designed for manually dimming luminaires that have a 1-10V interface.
- It has a fuse (Sicherung 16)) and trimmer (Trimmer 17)) for optimal performance.
- The product comes with two wiring schemes (Anschluss-Schema 1 and Anschluss-Schema 2) for easy installation.
- It can directly connect to an electrical load (Direkter Anschluss der el. Last20)) and can handle up to 6A resistive load or a maximum of 10 single lamp ECG or 5 double lamp ECG (21)).
- The control output can connect up to 100 OSRAM ECG (electronic control gear) that require a maximum of 100mA. For bigger loads, an external relay is necessary (23)).
- The DIM MCU G2 requires an electrical power supply of 220-240V~ at 50/60Hz and has a VAC El. power loss of 2%.
Product Usage
- Before installation, ensure that the electrical power supply is switched off.
- Refer to the wiring schemes (Anschluss-Schema 1 and Anschluss-Schema 2) provided in the user manual to connect the DIM MCU G2 to the luminaire and electrical load.
- Ensure that the fuse (Sicherung 16)) is inserted correctly and the trimmer (Trimmer 17)) is set to the desired level.
- If connecting to an electrical load (Direkter Anschluss der el. Last20)), ensure that the load does not exceed 6A resistive load, or a maximum of 10 single lamp ECG or 5 double lamp ECG (21)).
- If connecting to up to 100 OSRAM ECG, ensure that the total power consumption does not exceed 100mA, otherwise an external relay is necessary (23)).
- Once all connections are made, switch on the electrical power supply and test the DIM MCU G2 to ensure proper dimming functionality.

Application and function
The DIM MCU G2 control unit enables the brightness of up to 100 luminaires
with a 1-10V interface to be set manually. The integrated switching contact
can switch a current of up to 6A directly (Wiring scheme 1); an external load
relay must be used for bigger loads (Wiring scheme 2). The control current of
the 1-10V output is restricted to 100mA.
Commissioning
Adjusting the minimal brightness level (optional):
- Lights on
- Turn the knob all the way to the left.
- Remove the cover
- Turn the trimmer (footnote) to adjust the minimum brightness
- Replace the cover
Operation
-
a) Switching the light on and off:
Briefly press the knob. The switching direction will change each time the knob is pressed -
b) Increasing brightness:
Turn the knob to the right to increase brightness. -
c) Reducing brightness:
Turn the knob to the left to decrease brightness.
SAFETY AND MOUNTING INFORMATION
The DIM MCU G2 has been specifically designed to be mounted in flushmounted boxes complying to IEC 60670 standard; independent mounting is only permitted with appropriate cable clamps, sufficient insulation and resistance against fire. Connecting the control output (+ / -) to external voltages, especially with the mains voltage, will lead to the destruction of the device!
