1. Product Overview
The Skydance DA2 is a 2-channel constant voltage LED dimmer designed for DALI lighting systems. It supports both DT6 dimming and DT8-TC color temperature control modes, configurable via DIP switches. It also features PWM digital dimming and can be controlled with an external AC push switch for on/off and brightness/color temperature adjustment.
2. Safety & Warnings
- DO NOT install with power applied to the device.
- DO NOT expose the device to moisture.
- Ensure all wiring is performed by a qualified electrician and complies with local electrical codes.
- Verify input voltage and current ratings before connecting to power.
3. Setup and Installation
3.1 Mechanical Structures and Dimensions
The DA2 dimmer features an installation rack for mounting. The DALI bus input does not require distinguishing plus-minus polarity.
3.2 DIP Switch Configuration
The DA2 dimmer has DIP switches to configure its operating mode and PWM frequency.
DIP Switch 1: Light Type (DT6/DT8 Mode)
- DT6 2CH mode: Configures the dimmer for 2 DALI addresses and 2 channel output.
- DT8 TC mode: Configures the dimmer for 1 DALI address and 2 channel output (for color temperature control).
DIP Switches 2 and 3: PWM Frequency Setting
These switches set the output PWM frequency to 500Hz, 2KHz, 8KHz, or 16KHz. Higher PWM frequencies may result in lower output current and higher power noise, but are more suitable for camera use (to avoid flickers in video).
| PWM Freq | Iout (12-24V) | Iout (36-48V) |
|---|---|---|
| 500Hz | 10A | 8A |
| 2KHz | 9A | 7A |
| 8KHz | 6A | 5A |
| 16KHz | 5A | 4A |
3.3 Wiring Diagrams
Below are typical wiring configurations for the DA2 dimmer with different LED strip types and control methods.
- DA2 for single color (DIP switch 1 set to DT6): Connect the single color LED strip to the LED output terminals.
- DA2 for dual color (DIP switch 1 set to DT8): For color temperature control, channel 1 should be connected to the cool white LED strip, and channel 2 to the warm white LED strip.
- DA2 connect with AC push switch: Connect the AC push switch to the designated input terminals for manual control.
4. Operating Instructions
4.1 DALI Control
The DALI address for the DA2 dimmer is automatically assigned by the DALI Master controller. Please refer to the user manuals of compatible DALI Masters for specific operations and address configuration.
4.2 Push DIM Function
When connected to an external AC push switch, the following functions are available:
- Short press: Turns the light on or off.
- Long press (1-6 seconds): Initiates stepless dimming, with a dimming range of 1% to 100%. With every subsequent long press, the dimming direction (brighter/dimmer) will reverse.
- Double click: Switches between three preset color temperature levels: warm white, neutral white, and cool white, in sequence. After a double click, you can long-press to fine-tune the color temperature. The color temperature adjustment state will automatically exit after 5 seconds of no operation.
Note: When two DT6 addresses are used to control color temperature light, the two channels need to be respectively connected to the cool white LED strip and the warm white LED strip.
5. Maintenance
The Skydance DA2 DALI Dimmer is designed for reliable operation and requires minimal maintenance. Ensure the device is kept clean and free from dust. Periodically check all wiring connections for tightness and integrity. Do not attempt to open or repair the device yourself; refer to qualified personnel for any service needs.
6. Troubleshooting
If the device is not functioning as expected, consider the following:
- No light output: Check power supply connections, DALI bus connection, and LED strip wiring. Ensure DIP switch settings are correct for the intended light type.
- Incorrect dimming/color temperature: Verify DIP switch settings for DT6/DT8 mode and PWM frequency. Check DALI Master configuration and push switch functionality.
- Intermittent operation: Inspect all connections for loose wires. Ensure the device is not exposed to moisture or extreme temperatures.
If issues persist, consult the detailed user manual (PDF) or contact technical support.
