3 x 5amps per channel DMX controller and meets DMX512/1990 protocol. With variable voltage input it will operate on 12 Volt DC (96watt per channel) or 24 Volt DC (192 Watts per channel). Data input and output is by Cat 5 cable with RJ45 connectors, and must be used in conjunction with the one of the DMX Interface units. Up to eight DMX controllers can be connected to the DMX interface before the DMX amplifier (DMX – Split) must be used to stop degradation of the signal. The DMX controller connects to the lights to be operated and the power supply for the lights connecting to the DMX controller.
