the most advanced PWM (Pulse Width Modulation) digital dimming technology, especially design for single color led strip. For instance, point source of light, flexible light strip, led modules, led strings and so on. Belong to low-voltage DC power input and output with two interfaces, including V+ is the positive interfaces, the other one for the negative interface. Meanwhile, you can turn on/off, adjust brightness for different lighting effects through RF 14keys remote control. In addition, It is convenient to use RJ45 connector to connect the multiple controllers together, and achieve the synchronization function of thousands meters led strips.
