DA4-D DALI 4-Channel Constant Voltage DIN Rail LED Controller | DALI 2 Certified | 12-48V Input
The DA4-D is a versatile, 4-channel constant voltage DALI LED dimmer designed for LED strips. It supports DT6 single colour dimming, DT8 colour temperature (TC), DT8 RGB, and DT8 RGBW lighting types, allowing flexible integration based on specific lighting requirements. The device is compatible with DALI 2 protocols and can be DIN rail mounted, making it suitable for both professional and high-end residential installations.
Key Features:
- Dimming Modes: Supports DT6 for single-colour dimming, DT8-TC for tunable white (CCT) control, and DT8-XY for precise RGB and RGBW colour mixing, ensuring flexible and seamless lighting adjustments.
- Multi-channel Addressing: In DT6 mode, the controller supports 1 to 4 DALI addresses, with each of the 4 channels working separately, allowing for independent control and highly configurable setups.
- DALI 2 Certified: The controller is compliant with DALI standard protocols IEC 62386-102, IEC 62386-207, and IEC 62386-209, ensuring interoperability with other DALI-certified products.
- PWM Frequency Selection: Choose from 1000/2000/4000/8000/16000 Hz, suitable for different lighting effects, including no flicker for video applications. Higher PWM frequencies are better suited for video, reducing flicker.
- Input and Output: Input voltage range of 12-48V DC with an output of 5A per channel at 12/24V and 3A per channel at 36/48V, providing up to 576W of power for larger installations. Compatible with a range of LED strip voltages, ensuring flexibility.
- Digital Display: Easy setup with a digital display to manually assign DALI addresses or let a DALI master handle it automatically. The display also shows error notifications, like overload (OLA) and overheating (OHA).
- Control Options: Works with both DALI and an external AC push switch for versatile control, including on/off, brightness, and RGB colour adjustments. Note that DALI and AC push interfaces are compatible but should not be used simultaneously.
- Protection Features: Built-in overheat, overload, and short circuit protection with automatic recovery. The controller also has a fast self-testing function to ensure functionality and reliability.
- Mechanical Features: DIN rail mounting with standard TS-35/7.5 or TS-35/15 rails, making it easy to install in control panels. Dimensions: L120 x W78 x H55mm.
- Temperature Range: Operating temperature from -20℃ to +55℃ with a case temperature limit of +85℃. IP20 rating for indoor use only.
- Warranty: Comes with a 3-year standard warranty, extendable to 5 years with our extended warranty option.
The HL-DA4-D is perfect for any project needing dynamic lighting control with advanced DALI dimming capabilities. It can easily be set to operate in multiple modes, whether DT6 or any DT8 configuration, making it an ideal solution for architectural lighting, commercial environments, or complex residential setups.
The DA4-D supports multiple DALI-2 DT modes, making it a versatile and reliable choice for a range of LED strip configurations:
- Single Colour (1 Channel) – Operates in DT6 mode for smooth dimming control.
- Tunable White (CCT, 2 Channels) – Uses DT8 TC mode to seamlessly adjust the colour temperature between warm and cool white.
- RGB (3 Channels) – Controlled via DT8 XY mode, ensuring precise colour mixing using CIE 1931 XY coordinates.
- RGBW (4 Channels) – Operates in DT8 XY mode, blending RGB and white for consistent and accurate colour reproduction.
With DALI-2 certification, multi-channel addressing, and advanced PWM dimming, the DA4-D offers smooth and flexible lighting control, making it ideal for professional and residential applications.
