Product Information
Eliminate signal degradation and ensure uniform brightness across large-scale lighting projects with the Ltech LT-3040-CC Constant Current Power Repeater. Designed for complex installations, this 4-channel amplifier takes a single PWM input from your master controller and flawlessly reproduces it across four separate outputs. Its key advantage is the versatile 3-in-1 current selection, allowing you to set each of the four channels to 350mA, 700mA, or 1050mA via simple DIP switches. This flexibility makes it an essential component for driving various types of constant current LED loads in architectural, commercial, and landscape lighting. As an official upgrade to the LT-3090-350, the LT-3040-CC offers robust performance within the professional Ltech control system.
Key Features
Flexible 3-in-1 Current Output
Easily select 350mA, 700mA, or 1050mA per channel using onboard DIP switches to perfectly match your LED requirements.
4-Channel PWM Amplification
Drive up to four independent runs of constant current LEDs from a single control signal, ensuring perfect synchronization.
Wide Voltage Compatibility
Accepts a broad DC 12V to 48V input, making it compatible with a wide range of professional power supply systems.
High Power Capacity
Delivers up to 48.3W per channel for a total maximum output of 193.2W, ideal for powering extensive lighting installations.
Perfect Signal Integrity
Receives and re-transmits the PWM signal to eliminate issues like flickering or delayed response in long wiring runs.
Technical Highlights
- Photoelectric isolation technology between input and output ports prevents signal interference.
- High PWM frequency support ensures smooth, flicker-free dimming across all connected LEDs.
- Screw-down terminal power connections provide secure and reliable wiring.
- Compact and durable housing designed for easy integration into control cabinets.

Application Scenarios
How to Install & Use This Power Repeater
- Disconnect all power before installation.
- Mount the LT-3040-CC securely in a dry, well-ventilated location, away from direct heat sources.
- Connect the DC output from your power supply to the 'POWER' input terminals (V+, V-). Ensure the voltage is between 12V and 48V.
- Connect the PWM signal from your main LED controller to the 'SIGNAL IN' terminals.
- Use the DIP switches to set the desired constant current (350mA, 700mA, or 1050mA) for each of the four output channels. Ensure this matches the specification of your LED fixtures.
- Connect your constant current LED loads to the 'OUTPUT' terminals (CH1, CH2, CH3, CH4), verifying correct polarity.
- Once all connections are secure, restore power and test the system with your controller.
- The input voltage of the power supply must match the voltage requirements of your LED lights.
- Ensure the total power consumed by LED fixtures does not exceed the 193.2W maximum rating of the repeater.
- Using the incorrect current setting can damage your LEDs. Always verify the required current of your fixtures before connecting.

Frequently Asked Questions
Q: What is the main purpose of a constant current power repeater?
A:A power repeater amplifies and regenerates the control signal from a master controller, allowing you to extend the length of your LED installation or add more lights than the controller could handle alone, without signal loss or voltage drop issues.
Q: How do I select the output current on the LT-3040-CC?
A:The output current is set using the physical DIP switches on the unit. You can independently select 350mA, 700mA, or 1050mA for each of the four output channels.
Q: Can I use this to control four different colors or scenes independently?
A:No, this is a signal repeater. It takes one PWM input signal and duplicates it across four channels. To control channels independently, you would need a 4-channel controller sending signals to this repeater.
Q: What type of LED lights should I use with this repeater?
A:This device is designed specifically for constant current (CC) LED fixtures and modules. It is not compatible with standard constant voltage (CV) LED strip lights.
Q: How many LEDs can I connect to one channel?
A:This depends on the forward voltage (Vf) of your individual LEDs. You can connect LEDs in series as long as their total voltage does not exceed the output voltage range (3V-46V).
Q: Is the LT-3040-CC a standalone controller?
A:No, it is a signal amplifier that must be used in conjunction with a separate PWM LED controller, which provides the dimming or color-changing signal.
