LED Signal Amplifier Repeater – 4CH 6A per Channel
The 4-channel LED signal amplifier (also known as an LED repeater or booster) extends the reach of PWM control signals in large-scale LED installations. By accepting the PWM signal from a primary controller and replicating it with fresh power from a secondary power supply, this amplifier enables unlimited expansion of LED strip runs without signal degradation or voltage drop. Each of the 4 channels handles 6A independently, providing up to 288W total at 12V or 576W at 24V.
The amplifier operates in a transparent passthrough mode, faithfully reproducing the input PWM signal timing, frequency, and duty cycle without introducing latency or artifacts. Compatible with any PWM controller operating at frequencies from 100Hz to 20KHz, including common 2.4GHz RF, WiFi, DMX, DALI, 0-10V, and Bluetooth controllers. An LED status indicator confirms signal lock on each channel.
Multiple amplifiers can be cascaded in series for installations spanning hundreds of meters, with each amplifier refreshing the signal quality. The unit features isolated input and output stages (opto-coupled) that prevent ground loops and protect primary controllers from downstream faults.

Essential for large commercial installations: shopping mall cove lighting, airport terminal accent strips, stadium perimeter LED runs, building facade outlines, and any scenario where LED strip length exceeds the current capacity of a single controller. Use one amplifier per additional power supply to maintain consistent brightness across the entire installation.
