The main application of the DC mini 3-key controller: It is used as an online controller for RGB light strips, RGB controller remote control, and micro control. Power rate: can be connected to 72W. Dynamic effects: 19 static states: 20 dynamic effects. Speed levels: 8 levels. Brightness adjustment levels: 8 levels. PWM control levels: 256 large output power supply: 3*2A, maximum output power: 72W, overall machine size: 42*12*3MM, mini seven-color LED light bar controller (common sun), 19 dynamic effects. 20 static effects. It comes with up to 19 dynamic effects and 20 static colors! It achieves the performance of similar products. Through the touch buttons on the slender body, you can conveniently adjust various modes, speeds, colors and brightness. This machine also features a memory function and an output power of up to 144W. Installation steps: 1. Insert the light strip plug into the OUTPUT socket. The arrow on the light strip plug should correspond to the triangular arrow on the OUTPUT. 2. Connect the cable marked +12V to the +12V power supply in the color shown in the diagram, and ensure good insulation and no short circuit. 3. Supply power and start working. And please ensure that the insulation of the joints is good and there is no short circuit. Key instructions: 1. MODE key: Dynamic mode key. Pressing the MODE key will cycle through 19 dynamic effects, with each press switching to a new dynamic effect. Press and hold the MODE key for more than one second to switch to the demonstration mode. In the demonstration mode, various dynamic modes will be automatically cycled for demonstration. 2. COLOR Key: A static COLOR key. Pressing the Color key switches between 20 static colors, with each press switching to a different static color. 3. SPEED/BRIGHT keys: Function adjustment keys. Pressing this key in dynamic mode can adjust the speed of the dynamic mode. The dynamic speed is divided into 8 levels, and each press switches to a different speed. In the COLOR mode, the brightness of the light bar can be adjusted. The brightness is also divided into 8 levels, and each press switches to a different brightness level. 4. Power on/off function: Press and hold the SPEED/BRIGHT key for about 3 seconds to power off. After power off, press the SPEED key to restore it to the state before power off. Note: 1.
