DM02A02KNX is a universal KNX 2 channel dimmer with automatic identification of the type of load and with adjustable parameters to optimize the control of different types of lamps such as LEDs, incandescent and halogen lamps, dimmable compact fluorescent lamps (CFL), low voltage lamps with electronic or ferromagnetic transformer.
The 2 channels can be used independently or combined to drive higher power loads; always respect the maximum power values indicated in the table of this instruction sheet and check in the handbook how to configure the outputs as combined in ETS. To define the maximum load and in particular the maximum number of lamps that can be connected, the DimmerLoadTester software is available; with it is possible to analyze the peak absorption of a single lamp and calculate the maximum number of lamps that can be connected.
Each output channel can be used in the following configurations:
Trailing Edge [RC]: The dimmer turns off part of the final part of the waveform of the input voltage resulting in reduced lamp output. This load regulation is used for resistive or capacitive loads (typically halogen lamps with electronic transformer or incandescent lamps)
Leading Edge [L]: The dimmer turns off part of the initial part of the waveform of the input voltage, resulting in reduced lamp output. This load regulation is used for inductive loads (typically ferromagnetic transformers or toroidal)
