Description
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.

Frequently Asked Questions
What is the difference between IP65, IP67, and IP68?
IP65 handles surface splashes only and is not suitable for UK outdoor conditions or bathroom wet zones under BS7671. IP67 is rated for temporary immersion and covers outdoor garden installations, most bathroom zones, and exposed architectural features. IP68 handles continuous submersion for ponds, fountains, and fully exposed outdoor applications. For most UK garden and decking projects, IP67 is the correct choice.
Can I cut this product to a custom length?
Yes. ATOM LED products can be cut at the marked cut points without voiding the warranty. Many competitors restrict cuts to 50–100mm intervals, which wastes offcuts on tight custom runs. Use sharp scissors or a craft knife for a clean cut, then seal the end with a suitable end cap.
What size driver do I need?
Multiply the total metres by the wattage per metre, then add 20% headroom. For example: 10 metres of 24V neon flex at 9W/m = 90W total, so you need a minimum 108W driver. Never load a driver above 80% capacity for long-term reliability.
Should I choose 12V, 24V, or 48V?
Choose 12V for caravans, cars, boats, and any project powered by a 12V battery. Choose 24V for most home and trade installs where you need dependable run length with lower voltage drop. Choose 48V for longer architectural runs where extra distance and single-feed flexibility matter. For underwater or submerged installs, use IP68 Waterproof lights and the correct driver for that product; do not use 48V underwater.
What is your warranty?
ATOM LED offers product-specific warranties: up to 7 years on single-colour COB strip, 5 years on RGB and RGBW COB strip, and 4 years on LED neon flex. The warranty covers manufacturing defects. Call 01952 370028 for warranty claims.
Do you offer free delivery?
Yes. Free UK delivery on 97% of products via Royal Mail 48-hour tracked. Free next day delivery on Mainland UK orders over £90 (order by 1pm, Mon–Fri).
