Connection Schemes
a. Non – Dim operation
(-0,5V/+0,9V)
1..10V
Ensure proper insulation of not connected wire terminals.
b. Dim operation
i. Non – Dim operation 3 wires LED module
2 wires LED Module 3 wires LED Module
a) Ensure proper insulation of not connected wire terminals.
b) The maximum input capacitance of all connected LED modules (dimmable) should be less the 130nF.
c) Required type of Potentiometer for use = 47kOhm.
ii. Control via 1…10 Dimmer

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
Dimmable LED load
Non Dimmable LED load
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
