This system is a high-performance RGB led touch remote controller， adopting the most advanced PWM control technology， controlling all RGB led products with Four lines and four circuits( common anode)，owning 640 thousand colors and 20 automatical changing modes to choose.Also， It has the memory function(that is to say， the previous settings will be resumed when power on again).It is widely used in led RGB LED strip light， led module and so on.With the technology of the 2.4G high frequency wireless remote control， it has the the characteristics of low power consumption， long distance transmission， and strong anti-interference ability ，high speed telecommunications， etc.The remote looks fashionable and elegant ， with simple and practical functions of color changing and brightness dimming， the capacitive touch screen design makes the remote easy to use .The modular design and easy screwed terminals enable the controller easy to match with all kinds of led light products. Specification: Voltage: DC12V~24V Size: 85*45*23mm Control way: RGB three channels Max Load per channel: 6A Total output current: 18A Power: 12V: 216W， 24V: 432W Output connection: common anode Telecontrol distance: 30 meters Programs: 9 kinds Grouping of several lights:You can add an endless numbers of lights to a zone on the 4 channel remote by linking the lights to different zones. This way you are completely flexible in creating different group combinations. Attention:Please check whether the input voltage of the constant voltage power supply is in accordance with the controller， and please check the connection of both the cathode and anode， otherwise the controller will be broken.Please don't connect wires with power on. Please switch on again only when it is in right connection and no short circuit.Please keep your finger off the touch ring when installing the batteries， to improve its sensitivity， and use the remote (3 seconds later) after the batteries are installed. Please reinstall the batteries， if the touch ring is found low-sensitivity.Please do not use the controller in the place with widely range metal area or strong electromagnetic wave nearby， otherwise， the remote distance will be seriously affected. Packing included: 1 x DC12V~24V 4-Zone Control 2.4G RGB Controller
