Application Scenarios
How to Control & Use This Wireless Receiver
- Ensure power is off before wiring.
- Connect your DC5-24V power supply to the 'INPUT' V- and V+ terminals on the F4-5A.
- Connect your LED strip lights to the 'OUTPUT' terminals. The common anode (V+) connects to the V+ terminal, and the negative wires connect to CH1, CH2, CH3, and CH4.
- Press the 'Learning key' button on the F4-5A receiver. The indicator light will turn on.
- Immediately press the desired zone button on your compatible F-series remote or EX series touch panel. The receiver's indicator light will flash to confirm successful pairing.
- To add app control, pair the F4-5A with a WiFi-106 gateway by following the gateway's user manual.
- Power on the system and test your lighting control.
- Always use a power supply with a voltage that matches your LED strips (e.g., a 24V power supply for 24V strips).
- Do not exceed the maximum load of 5A per channel or 20A total for the receiver.
- Ensure proper ventilation around the receiver to prevent overheating.
- This is a constant voltage receiver. Do not use it with constant current LED fixtures.

Frequently Asked Questions
Q: What types of LED lights can the F4-5A control?
A:The F4-5A is a 4-in-1 controller for constant voltage LED lights, including single color, CCT (tunable white), RGB, and RGBW strips.
Q: What is the main difference between the F4-5A and the F4-3A model?
A:The F4-5A has a higher current capacity of 5 Amps per channel, compared to the F4-3A's 3 Amps per channel. This makes the F4-5A suitable for more powerful or longer LED strip installations.
Q: Do I need a remote control to use this receiver?
A:Yes, this is a receiver only. You need a compatible Ltech F-series remote or EX-series touch panel to send it a control signal.
Q: Can I control this receiver with my smartphone?
A:Yes, you can control the F4-5A with a smartphone app by pairing it with an Ltech WiFi-106 gateway (sold separately).
Q: What kind of power supply is required?
A:You need a constant voltage DC power supply with an output voltage that matches your LED strips (e.g., DC 12V or DC 24V). The power supply's wattage must be sufficient to handle the total load of your strips.
Q: How many F4-5A receivers can I pair to a single remote zone?
A:You can pair multiple F4-5A receivers to the same zone on a remote to synchronize control over a large area.
