Product Information
The Ltech LT-3030-6A is a high-performance Constant Voltage (CV) power repeater designed to extend and amplify the control signal for large-scale LED lighting systems. When your LED strip installation exceeds the power capacity of your main controller, the LT-3030-6A seamlessly takes over, powering additional strip sections while maintaining perfect synchronization. With three channels rated at 6A each for a total of 18A, it effortlessly drives long runs of RGB or single-color LED strips, eliminating the brightness loss and color inaccuracy caused by voltage drop. Its wide DC5V-24V input range makes it a versatile solution for any low-voltage PWM-controlled lighting project, ensuring every LED shines with consistent, flicker-free intensity from beginning to end.
Key Features
High-Current Capacity
Delivers a robust 6A per channel across three channels, with a maximum total output of 18A for demanding LED loads.
Wide Voltage Compatibility
Operates on any DC voltage from 5V to 24V, making it compatible with a vast range of constant voltage LED strips.
Flicker-Free PWM Amplification
Receives and boosts PWM control signals with high fidelity, ensuring smooth dimming and perfect color sync with the master controller.
Eliminates Voltage Drop
Powers subsequent sections of long LED runs, guaranteeing uniform brightness and consistent color along the entire length.
Simple & Reliable Wiring
Features clearly labeled screw-down power terminals for secure, straightforward connections in any installation.
Engineered for Flawless Signal Integrity
- High-speed optocoupler isolation on the input port protects against signal interference.
- PWM signal regeneration ensures no delay or degradation, maintaining perfect sync across hundreds of feet.
- Efficient power handling minimizes heat generation for stable, long-term operation.

Application Scenarios
How to Install and Use This Power Repeater
- Safety First: Always disconnect all power sources before making any wiring connections.
- Connect Power Supply: Run wires from a separate LED power supply to the 'POWER' input terminals (V+, V-) on the LT-3030-6A. The power supply voltage must match your LED strips (e.g., 24V for 24V strips).
- Connect Control Signal: Connect the PWM signal output from your master LED controller to the 'SIGNAL' input terminals (CH1/R, CH2/G, CH3/B, and V+) on the repeater.
- Connect Additional LEDs: Wire the next segment of your LED strip run to the corresponding 'OUTPUT' terminals (CH1/R, CH2/G, CH3/B, and V+) of the repeater.
- Verify Polarity: Double-check all connections to ensure correct polarity (+ to +, - to -) to prevent damage to your equipment.
- Power On: Reconnect the power and test your lighting system. The newly connected LED strip section should now operate in perfect synchronization with the strips connected to the main controller.
- The LED power supply connected to the repeater must be sized to handle the load of the LED strips it will be driving.
- Do not exceed the maximum current rating of 6A per channel or 18A in total for the repeater.
- This is a Constant Voltage (CV) power repeater. It is only compatible with CV LED strips and fixtures.
- Ensure adequate ventilation around the repeater to maintain optimal operating temperature.

Frequently Asked Questions
Q: What does a CV power repeater do?
A:A CV (Constant Voltage) power repeater boosts the PWM control signal and provides fresh power to extend the length of your LED strip runs. This prevents voltage drop, which causes dimming and color shifting on long installations.
Q: My power strip light is flickering at the far end. Will this fix it?
A:Yes, a flickering light at the end of a long LED strip is a classic sign of insufficient power due to voltage drop. Installing this repeater with a second power supply will resolve the issue by providing ample, stable power to the end of the run.
Q: How many power repeaters can I use in one lighting system?
A:You can daisy-chain multiple repeaters to create very long runs. Each repeater in the chain must be connected to its own appropriately sized LED power supply to power its section of LED strips.
Q: Is this compatible with RGB LED strips?
A:Absolutely. The LT-3030-6A features three channels, which is perfect for standard 4-pin RGB LED strips. It can also be used to amplify three separate channels of single-color strips.
Q: What is the difference between this and a DMX decoder?
A:This power repeater amplifies an existing PWM signal from a standard LED controller. A DMX decoder's job is to convert a DMX512 signal into a PWM signal. They serve different functions and are not interchangeable.
Q: Can I use the LT-3030-6A for a 12V LED lighting project?
A:Yes, this repeater has a wide operating range of DC5V to DC24V, making it fully compatible with 5V, 12V, and 24V constant voltage LED lighting systems.
