- DALI-2 DT6 and T-PWM Dimming Support
- Selectable Output Current (100mA to 400mA)
- Wide Input Voltage Range (100-240V AC)
4. Setup and Installation
Follow these steps for proper installation of the LED driver.
4.1 Wiring Connections
The driver features clearly labeled terminals for input power, LED output, and dimming control. Ensure all connections are secure and comply with local electrical codes.
- Input (PRI): Connect the AC mains power to the 'N' (Neutral) and 'L' (Line) terminals.
- Output (SEC): Connect the LED module to the 'LED+' and 'LED-' terminals. Observe polarity.
- Dimming (DA): Connect the DALI or T-PWM control lines to the 'DA' terminals.
Wire Preparation: For all terminals, use wires with a cross-sectional area between 0.5mm² and 2.5mm² (approximately 20-14 AWG). Strip wires to the recommended length as indicated on the device (typically 8-9mm).
4.2 Current Selection (DIP Switches)
The output current of the LED driver can be set using the three DIP switches labeled '1', '2', and '3'. Refer to the table printed on the driver's label for the specific switch combinations corresponding to each output current.
| Output Current (mA) | Output Voltage Range (V) | DIP Switch 1 | DIP Switch 2 | DIP Switch 3 |
|---|---|---|---|---|
| 100 | 9-42 | OFF | OFF | OFF |
| 150 | 9-42 | ON | OFF | OFF |
| 200 | 9-42 | OFF | ON | OFF |
| 250 | 9-42 | ON | ON | OFF |
| 300 | 9-40 | OFF | OFF | ON |
| 350 | 9-34 | ON | OFF | ON |
| 400 | 9-30 | OFF | ON | ON |
Important: Adjust DIP switches only when the driver is disconnected from power.
5. Operating Instructions
Once installed and configured, the LED driver operates automatically. Dimming control is achieved through external DALI-2 or T-PWM signals connected to the 'DA' terminals.
- Power On: After all connections are made and verified, restore power to the circuit. The connected LED module should illuminate.
- Dimming Control: Use a compatible DALI-2 or T-PWM dimmer/controller connected to the 'DA' terminals to adjust the brightness of the LED module.
- Flicker-Free Operation: The driver is designed to provide stable, flicker-free light output across its dimming range.
6. Maintenance
The NYGOXSXA SE-12-100-400-W1DS LED Driver requires minimal maintenance. Regular inspection can help ensure long-term reliable operation.
- Cleaning: Periodically clean the exterior of the driver with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Inspection: Annually inspect wiring connections for tightness and signs of wear or damage. Check for any discoloration or unusual odors.
- Ventilation: Ensure that the driver's ventilation is not obstructed to prevent overheating.
In case of malfunction, do not attempt to repair the driver yourself. Contact qualified service personnel.
7. Troubleshooting
If you encounter issues with your LED driver, refer to the following common troubleshooting steps:
- No Light Output:
- Verify that power is supplied to the driver.
- Check all wiring connections (input, output, dimming) for proper contact and polarity.
- Ensure the LED module is compatible with the selected output current and voltage range.
- Confirm the LED module itself is functional.
- Incorrect Brightness or Flickering:
- Verify the dimming control signal (DALI-2 or T-PWM) is correctly connected and functioning.
- Ensure the selected output current via DIP switches matches the requirements of the LED module.
- Check for loose connections in the dimming circuit.
- Overheating:
- Ensure the driver is installed in an area with adequate ventilation.
- Verify that the ambient temperature (ta) does not exceed 50°C.
- Confirm the LED load does not exceed the driver's maximum output power (12W).
If the problem persists after following these steps, discontinue use and contact the manufacturer or a qualified technician.
