Available in six-channel and twelve-channel versions, the DMX2CC enables DMX512 control of high power LEDs (1 W and 3 W) using a constant current dimming method, ensuring flicker-free and smooth dimming as it is, for instance, required in such environments as television studios or in the field of medicine. The DMX512 out port repeats and amplifies the DMX512 signal for convenient daisy-chaining. Additionally, a self-diagnostic test function prevents damage to the unit and LEDs caused by incorrect wiring, open or short circuit, and overheating, and is able to maintain lighting levels in times of DMX512 data and signal loss. DMX2CC is easily set up with auto and manual DMX512 addressing modes, and conveniently mountable inside equipment racks using standardized 35 mm wide DIN rail.
