3. Low Power LEDs

 

3.1 Why not choose one single supply voltage?
3.2 Differences in colour and intensity?
3.3 Why to use a stabilised DC voltage power supply in stead of a common transformer?
3.4 Full load of a DC supply?
3.5 Maximal distance and cable cross-section between the DC supply and LED module?

4. High Power LEDs

 

4.1 Why are High Power LEDs driven by stabilised direct current supply instead of a voltage power supply?
4.2 What determines the current by which the High Power LED’s are driven?
4.3 Do LED modules need to be connected with the supply, before are after the mains voltage is switched on?
4.4 Maximal distance and cable cross-section between the DC current supply and the LED module?

5. Low Power Multi-Colour LEDs (RGB)

 

5.1 Why does the RGB Driver DMX only applies 3 out of the 512 DMX channels?
5.2 Why to use a DMX cable with 5 pins XLR connector to transmit the DMX signal?
5.3 Do the 3 outputs of the RGB Booster 200 correspond with the set ups of the RGB colours?
5.4 Why are maximal 10 strips 20LS06 in line allowed and why is the distance from the Junction Box RGB to the last module limited to 5m?
