Wiring Diagram (General)
The EV4-D has terminals for power input, signal input from the LED controller, and power output to the LED strips. Ensure all connections are secure and polarity is correct (positive to positive, negative to negative).
- Power Input (DC IN): Connect a 12-24VDC power supply to the "DC IN" terminals. Ensure the power supply capacity meets the total power requirements of your LED installation.
- Signal Input (DATA IN): Connect the output signal from your LED controller to the "DATA IN" terminals. Match the channels (e.g., R to R, G to G, B to B, W to W for RGBW systems, or common anode/cathode for single color).
- Power Output (LED OUT): Connect your LED strips or modules to the "LED OUT" terminals. Each channel (CH1, CH2, CH3, CH4) can drive up to 5A. Ensure the total current for all connected LEDs does not exceed 20A.
- Grounding: Ensure proper grounding for all components in your LED system.
Note: Specific wiring details may vary depending on your LED controller and LED strip type (e.g., common anode or common cathode). Always refer to the wiring instructions of your LED controller and LED strips.
6. Operating Instructions
The Optonica EV4-D power repeater operates as an amplifier for your existing LED controller. It does not have its own control interface. Once correctly wired, the repeater will automatically amplify the signals it receives from the primary LED controller.
- Ensure the LED controller is powered on and functioning correctly.
- The EV4-D will mirror the dimming, color changes, and mode selections made on your primary LED controller.
- If using multiple repeaters for very large installations, ensure consistent power supply and signal integrity across all units.
7. Maintenance
The Optonica EV4-D power repeater requires minimal maintenance to ensure long-term performance.
- Cleaning: Periodically clean the exterior of the device with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Inspection: Regularly check all wiring connections to ensure they are secure and free from corrosion or damage.
- Ventilation: Ensure that the ventilation openings are not obstructed to allow for proper heat dissipation.
- Environment: Keep the device in a dry, dust-free environment within its specified operating temperature range.
8. Troubleshooting
If you encounter issues with your Optonica EV4-D power repeater, refer to the following common troubleshooting steps:
- No Power to LEDs:
- Check the power supply connection to the EV4-D. Ensure it is securely connected and providing the correct voltage (12-24VDC).
- Verify the power supply itself is functional.
- Check the connections from the EV4-D to the LED strips. Ensure correct polarity and secure connections.
- LEDs Not Responding to Controller:
- Ensure the signal input from the LED controller to the EV4-D is correctly wired and secure.
- Verify that the LED controller itself is functioning correctly and sending a signal.
- Check for any breaks or damage in the signal cables.
- Flickering or Inconsistent LED Brightness:
- Ensure the power supply is adequate for the total load of the connected LEDs. An undersized power supply can cause flickering.
- Check for loose connections at both the input and output terminals of the EV4-D.
- Verify that the LED strips themselves are not faulty.
- Overheating:
- Ensure the device is not enclosed in a way that restricts airflow.
- Verify that the total current drawn by the LEDs does not exceed the 20A maximum capacity of the repeater.
If these steps do not resolve the issue, please contact customer support.
