The Berker 2998 DALI Rotary Potentiometer is a specialized control device engineered for the precise management of Tunable White lighting systems. By integrating a power supply directly into the unit, this device simplifies the installation process for DALI-based lighting networks, allowing users to adjust both light intensity and color temperature seamlessly through a single rotary interface. It is designed to meet the demands of professional electrical installations, ensuring consistent performance and intuitive operation in various indoor settings.
Advantages
The primary benefit of this potentiometer is its all-in-one design, which combines control functionality with an integrated power supply to reduce the need for external components. Its rotary mechanism provides tactile and accurate feedback, making it easy to fine-tune lighting environments to specific preferences. The device is built for durability and reliability, adhering to high standards for electrical components, which makes it an ideal choice for long-term use in both residential and commercial lighting projects.
Suitable for
- Adjusting color temperature in Tunable White LED systems
- Manual dimming control in DALI-compatible lighting networks
- Professional lighting management in offices and retail spaces
- Residential smart lighting installations requiring manual overrides
When it may not be suitable
This device is specifically designed for DALI-based systems and will not function in standard analog or non-DALI lighting circuits. It is not intended for outdoor use or environments with high humidity, as it lacks the necessary ingress protection ratings for such conditions.
Key specifications
- Control interface: Rotary potentiometer
- Compatibility: DALI protocol
- Lighting support: Tunable White
- Integrated power supply: Included
- Installation type: Flush-mounted
How to use
The device should be installed by a qualified electrician into a standard flush-mounted wall box. Once connected to the DALI bus and the compatible luminaires, the rotary knob allows for manual adjustment. Turning the knob typically modifies the light intensity, while additional interaction or specific configuration allows for the adjustment of the color temperature, depending on the setup of the connected DALI drivers.
What to consider before purchase
- Ensure your lighting system supports the DALI protocol
- Verify that your luminaires are Tunable White compatible
- Check that the total power requirements of your lighting system are within the capacity of the integrated power supply
- Confirm compatibility with your existing wall switch frames and cover plates
Usage recommendations
For optimal performance and safety, ensure that all wiring is performed according to local electrical codes and that the DALI bus is correctly terminated. Avoid exceeding the maximum load capacity specified for the integrated power supply to prevent system instability.
