RGB Controller LTC LXL157+ – controller for RGB LED strings, 12–24V compatible

LTC LXL157+ is an RGB controller designed to manage RGB LED strings and strips operating from low-voltage DC supplies. The device supports 12–24 V input and provides separate outputs for red, green and blue channels to enable accurate color mixing and adjustable brightness. It is intended for decorative lighting, signage and ambient illumination where centralized control of RGB color and dimming is needed.

Advantages

The controller provides channelized PWM output for each color channel, allowing smooth color transitions and stable dimming across a variety of LED load types. Compatibility with 12–24 V systems makes it suitable for common LED strip installations without requiring additional converters. Its compact design simplifies installation in retrofit or new-build projects and helps integrate RGB control into lighting systems for both indoor and sheltered outdoor applications.

Suitable for

• RGB LED strips and strings in decorative and accent lighting
• Illuminated signage and display backlighting
• Ambient lighting for retail, hospitality and residential spaces
• Low-voltage lighting installations where color mixing and dimming are required

Key specifications

• Input voltage range: compatible with 12–24 V DC systems
• Output type: separate channels for red, green and blue with PWM dimming control
• Control capability: independent control of three color channels for color mixing and brightness adjustment
• Installation: compact form factor suitable for mounting near LED power supplies or inside lighting enclosures

How to use

Connect a suitable 12–24 V DC power supply to the controller input, then wire the red, green and blue outputs to the corresponding leads of the RGB LED strip or string. Ensure correct polarity and secure connections. After wiring, apply power and use the compatible control interface (remote, wall panel or system input as applicable) to adjust color and brightness. Verify that the power supply can deliver sufficient current for the total LED load to avoid voltage drop or overheating.

Usage recommendations

For reliable operation, use a power supply sized to the total wattage of the connected LED load and maintain wiring runs with adequate conductor size to reduce voltage drop. Avoid exposing the controller to direct water ingress; install in ventilated or protected enclosures if used in damp or outdoor-adjacent locations. When integrating with control systems, follow manufacturer guidance for interface compatibility and isolation to prevent electrical interference.
