iii. Single control of more power supplies

Control of more OT 80/220-240/24 DIM P to an external Dimmer/Potentiometer. Thanks to the fully isolated 1…10V interface, two different kind of
dimming devices are possible

1)

Potentiometer - the value will be 47K Ohm /

n where n is the number of Power supplies to be controlled

2)

Active Dimmer - Dimmer is connected to mains (see Figure 1c)

iv. Combination of “dimmable” and “non dimmable” LED Modules


The maximum input capacitance of all connected LED modules (dimmable) should be less the 130nF.


3. Safety

Power supplies can be connected in parallel on the primary side, but not on the secondary side
