The Sunricher 2303P is a multifunction 4-in-1 LED dimmer that supports DALI, AC Push, 0-10V, and Phase Cut dimming interfaces. It is designed for 12-48V DC LED lighting systems with a maximum output current of 20A.
Safety & Warnings
- Do not install the device with power applied.
- Do not expose the device to moisture.
- Ensure wire specifications are 0.5-2.5mm² to handle the rated current.
- For AC Push and Phase Cut dimming, the input voltage range is 100-240VAC.
Operation
The device features a DIP switch to select the desired dimming interface. Before wiring, ensure the correct interface is selected on the DIP switch. Different dimming interfaces cannot be wired and used simultaneously; only one of the four can be active at a time.
Wiring Configurations
The device supports four distinct wiring modes:
- DALI Bus: Connects to DALI master controllers.
- AC Push: Standard AC push-button dimming.
- 0-10V: Connects to 0-10V control units.
- Phase Cut: Connects to Phase Cut/Triac dimmers.
Always ensure the power supply is compatible with the load and that the wiring is secure before applying power.
Technical Specifications
- Input Voltage: 12-48V DC
- Output Current: 1x20A
- Output Power: 1x(240-960)W
- Dimming Range: 0.1%-100%
- Operating Temperature: -20°C to +50°C
- Dimensions: 170 x 53.4 x 28 mm
- Waterproof Grade: IP20
Practical help
Common problems
Dimmer not responding to control signal
Verify that the DIP switch is set to the correct dimming interface (DALI, Push, 0-10V, or Phase Cut) and that only one interface is selected.
Overheating or wiring failure
Ensure wire gauge is between 0.5-2.5mm² and that the total load does not exceed the 20A maximum output current.
Before use
- Ensure power is disconnected before installation.
- Check that the input voltage (12-48V DC) matches your power supply.
- Verify the DIP switch setting matches your intended control method.
- Ensure wires are 0.5-2.5mm² to support the 20A load.
- Confirm the load does not exceed 960W.
