LTECH M4 + M4-5A RGBW LED Controller & Remote, 12–24V 20A

Control colour and a dedicated white channel from one handset with this LTECH RGBW LED controller kit. It pairs the M4 touch-wheel remote with the higher-capacity M4-5A receiver, making it suitable for constant-voltage RGBW LED tape where separate red, green, blue and white outputs are required.

Compatibility and control

The receiver works at 12–24V DC and responds to the supplied M4 remote over 433.92MHz RF. It is not a Wi-Fi or app controller. Match each RGBW conductor to the labelled receiver output and use a constant-voltage power supply sized for both the LED voltage and total load.

Key specifications

• Four 5A output channels; 20A maximum total

Before installation

The power supply and LED lighting are not included. Isolate power before wiring, confirm polarity and remain within every channel limit. Neither the receiver nor low-voltage LEDs may be connected directly to 220–240V AC mains. The shared manual also shows an M8 handset; this kit contains M4, so follow the M4 controls and M4-5A diagram. Keep coin cells secured and away from children.
