Application Scenarios
How to Control & Use This Controller
- Select Output Current: Before wiring, use the DIP switches on the receiver to select the correct constant current output (350mA, 700mA, or 1050mA) to match your LED fixtures' specifications.
- Wire Power Input: Connect a compatible 12V to 48V DC power supply to the receiver's 'INPUT' terminals. Ensure correct polarity (+ to +, - to -).
- Wire LED Output: Connect your constant current LED fixtures to the 'OUTPUT' terminals (CH1, CH2, CH3, CH4). Verify the polarity is correct for each channel.
- Pair with Remote: Follow the instructions for your Ltech LT-BUS remote control or wall panel to pair it with the F4-CC receiver. This typically involves pressing a learning key on the receiver while the remote is in pairing mode.
- Test Operation: Once paired, test the dimming and on/off functions for each connected channel to confirm the system is working correctly.
- Always disconnect power before wiring or changing DIP switch settings.
- Ensure your power supply has a voltage within the receiver's 12-48Vdc input range.
- Do not exceed the total maximum power output of 193.2W.
- This receiver is designed for constant current LED fixtures only. Do not connect it to constant voltage LED strips.

Frequently Asked Questions
Q: What is the main difference between the F4-CC and the F4-5A receiver?
A:The F4-CC is a Constant Current (CC) receiver designed for fixtures like spotlights and downlights. The F4-5A is a Constant Voltage (CV) receiver used for products like standard LED strips.
Q: What kind of remote controls are compatible with the F4-CC?
A:This receiver works with any remote control or wall panel from the Ltech LT-BUS ecosystem. Please verify compatibility before purchasing a remote.
Q: Can I control four different single-color LED lights with this one receiver?
A:Yes, if your remote supports multi-zone control, the four channels can be managed independently to control four separate areas or fixtures.
Q: How do I select the output current?
A:The output current (350mA, 700mA, or 1050mA) is set using the physical DIP switches on the side of the unit. This must be done before you connect power.
Q: Is this a DMX receiver?
A:No, the F4-CC uses Ltech's proprietary LT-BUS wireless protocol. For DMX control, please see our F4-DMX-5A receiver or other DMX decoders.
Q: What kind of power supply do I need for this receiver?
A:You need a constant voltage DC power supply with an output between 12V and 48V. Ensure it can provide enough wattage for the total load of all your connected LED fixtures.
