LTECH M2 + M4-5A CCT LED Controller & Remote, 12–24V 20A

Move between warmer and cooler white light, then set the brightness, with this LTECH CCT controller and remote kit. The M2 touch-wheel handset operates an M4-5A receiver, providing a higher-current solution for compatible tunable-white, constant-voltage LED tape.

CCT compatibility

The receiver accepts 12–24V DC and its four outputs are used as warm-white and cool-white pairs in CCT mode. Follow the channel arrangement in the manufacturer diagram rather than assuming a two-terminal dimmer layout. Control is 433.92MHz RF only; Wi-Fi and app control are not included.

Key specifications

• M2 remote and M4-5A receiver supplied
• 5A per output channel; 20A receiver maximum
• Tunable-white colour-temperature and brightness adjustment
• Receiver dimensions: 175 × 44 × 30mm
• Short-circuit and overload protection
• M2 remote uses one 3V CR2032 coin cell

Installation essentials

Add a correctly rated constant-voltage supply and CCT LED lighting; neither is part of the kit. Keep the supply voltage aligned with the LED tape, calculate the current per output, isolate the circuit before wiring and check polarity. Do not connect any low-voltage component directly to UK 220–240V AC mains. Coin cells must remain secured and out of children’s reach.
