Mini RF LED Dimmer Controller with 433.92 MHz Remote – 12–24V DC

The LTECH Mini Series LED controller combines compact design with powerful performance, delivering reliable RF remote controlled dimming for low voltage LED lighting systems. With over 10 years of LED control development behind it, this controller is only one third the size of conventional units while still offering smooth dimming, RGB and colour temperature control options depending on configuration.

The included RF remote operates on 433.92 MHz with a wireless range of up to 50 metres, providing stable control without requiring line of sight. It features a touch sensitive dimming wheel for precise brightness adjustment, an on and off button, two programmable scene memory buttons for saving preferred light levels, and a convenient 30 second delay off function.

Designed for 12–24V DC LED circuits, the M3-3A receiver delivers PWM output for smooth and flicker free dimming. It supports a current load of 3A per channel with a maximum 9A total load, making it suitable for single colour LED strips and compatible RGB or colour temperature LED installations. The receiver can be paired with up to 10 remotes and includes a simple ID learning function for quick setup.

With compact dimensions, easy installation and a 5 year warranty, this mini RF LED dimmer controller is ideal for residential, commercial and architectural LED lighting projects where reliable wireless dimming is required.
