LTech LT-3040-5A – Professional RGBW Signal Amplifier & Power Repeater
Essential signal booster and power repeater for extending RGB/RGBW controller reach beyond standard voltage drop limitations. Accepts PWM control signals from any compatible RGB/RGBW controller and provides fresh power injection to maintain consistent brightness across extended LED installations. Features 3KV photoelectric isolation for signal protection and unlimited cascade capability for truly large-scale projects.
Signal Amplification Advantages:
-
Extended Range Capability – Overcome 5m (12V) and 10m (24V) standard controller limitations
-
High Power Handling – 4 channels × 5A each, up to 480W total output at 24V
-
Universal Compatibility – Works with 5-24V RGB/RGBW controllers and LED products
-
Unlimited Expansion – Cascade multiple amplifiers for extensive installations
-
Signal Protection – 3KV photoelectric isolation prevents interference and damage
-
Maintenance-Free Operation – No configuration required, simple signal pass-through design
Perfect Applications:
-
Large Channel Letters – Maintain brightness consistency across extensive signage installations
-
Architectural Lighting – Building facades and structures requiring long cable runs
-
Commercial Signage – Large-format displays where single controller range is insufficient
-
Entertainment Venues – Stage installations and venues with distributed LED requirements
-
Industrial Applications – Warehouses and facilities needing extended LED coverage
-
Retail Installations – Shopping centers and stores with widespread RGB lighting needs
Installation Advantages:
-
Simple Integration – Direct connection between controller and LED loads, no programming required
-
Flexible Mounting – Compact 175×44×30mm size fits in tight spaces and junction boxes
-
Professional Connections – Screw terminal inputs and outputs for reliable field connections
-
Temperature Resilient – Operates reliably from -30°C to +55°C for indoor and outdoor use
-
Multiple Power Options – Single amplifier supports 12V (240W) or 24V (480W) systems
System Expansion Made Simple:
-
Single Amplifier = Extends controller range by one additional zone
-
Multiple Amplifiers = Unlimited daisy-chain capability for large installations
-
Power Calculation = 100W@5V / 240W@12V / 480W@24V per amplifier
-
Installation Rule = Add amplifier every 5m (12V) or 10m (24V) of LED strip
-
System Planning = Controller → Amplifier → LEDs → Amplifier → More LEDs

System Integration & Planning
Installation Guidelines: Add one amplifier for every 5 metres of 12V LED strip or 10 metres of 24V LED strip beyond the controller's direct drive capability
Power Planning: Each amplifier requires dedicated power supply sized for connected LED load (separate from controller power supply)
Signal Chain: Controller → Amplifier #1 → LED Load → Amplifier #2 → More LED Load → Continue as needed
Cascade Capability: Theoretically unlimited amplifier chaining for large-scale installations
Connection & Installation
- Input Connections: PWM signal input from RGB/RGBW controller via screw terminals
- Output Connections: Amplified PWM signal output to LED loads via screw terminals
- Power Input: Separate 5-24V power input matching LED system voltage
- Professional Installation: Indoor mounting in dry location or weatherproof enclosure for outdoor use
- Ventilation Requirements: Maintain adequate airflow around unit for heat dissipation
Voltage Drop & Range Extension
Standard Controller Limitations:
- 12V Systems: 5 metre maximum effective range from controller
- 24V Systems: 10 metre maximum effective range from controller
With LT-3040-5A Amplification:
- Extend range indefinitely with proper amplifier placement
- Maintain full brightness and colour consistency across entire installation
- Each amplifier refreshes both signal and power for connected loads
