DMX system is a intelligent lighting control system for complicated lighting design and layout in large area. It enables to control all lighting devices in a building separately with only one master controller. The master controller transmits DMX signal to the slave controllers (lighting devices). The slaves receive and convert it to PWM signal to control the connected LED lamps. A DMX LED controller is a slave controller to control LED lighting, and it enables to control not only single color, but also CCT and RGB lighting. With a master controller, it enables light intensity, color temperature and RGB color adjustment. For RGB lighting, each R, G, B channel has 0-255 grey levels thus millions of colors can be achieved. The maximum signal transmission distance from the master to slave can be up to 500 meters, which means the signal can infrared heater (out)s Manufacturers reach any corner of a building. The master controller also supports different color sequences to create stunning lighting effects. There are various types of DMX LED controller depending on the lights to be connected. You should choose a proper one for your LED lamps based on their input type. AC version is designed for AC input LED lamps and DC version is designed for DC input LEDs, and the output type of DC version is available in constant current and constant voltage. For DC version, an AC to DC power supply is required to power the controller. DMX LED controller is reliable and stable for not only large lighting projects but also residential lighting to create different moods for different atmospheres. There are many styles of master controller available in the market, for instance, the keyboard style is a traditional one with many DMX channels output to control each individual lamp of a building. Simple and easy styles such as rotary switch and full touch panel with simple interface are available for home lighting control.
