Start with what the luminaire or LED strip requires. Casambi is the control system; the module's electrical interface determines how your particular light source can be connected and controlled.
1. Read the luminaire or driver label
Identify the exact model, supply and dimming interface before choosing a module. DALI, phase dimming, 0–10 V and constant-voltage strip describe different interfaces. A module for one must not be assumed to replace a module for another.
A luminaire that is already Casambi Ready may have control built in. Check its own profile and functions before ordering an additional module.
2. Match the interface to the appropriate model
The following is an initial selection guide. Always use the selected model's EU documentation for actual wiring, load limits and profile.
- A dimmable AC driver or AC lamp compatible with trailing-edge control: CBU-TED-LR is the relevant module family to check.
- A driver with 0–10/1–10 V or a suitable closed DALI arrangement: check CBU-ASD-LR. Its DALI supply and relay function have specific limitations.
- Two analogue 0–10 V channels or a suitable DALI port: check CBU-A2D-LR. The older CBU-A2D is a separate non-LR model.
- A DALI bus with an external bus supply: check CBU-DCS-LR and the correct profile. It takes power from the bus and does not provide its own bus supply.
- A 12–24 V constant-voltage LED strip: check CBU-PWM4-LR together with the correct power supply, channel profile and total current.
3. Decide what the user should be able to do
Dimming a single-colour strip, changing colour temperature and controlling RGB/RGBW require different loads and profiles. The app exposes the functions offered by the selected hardware. It does not turn a single-colour luminaire into a colour-changing one.
DALI broadcast sends common commands to the connected drivers. It does not automatically provide individual addressing of each luminaire. If an existing DALI system will control Casambi, or every DALI luminaire needs individual addressing, check the system direction and architecture separately.
4. Add the right way to operate the lights
Xpress-LR provides programmable button choices. A compatible sensor can provide presence and/or daylight functions once its model and profile are verified. Cloud Gateway provides agreed remote access and can help maintain network time; it is not a general requirement for local switch control.
Products labelled LR provide Long Range operation only in a compatible network set to Long Range radio mode. Check the whole network when extending it. Do not change an older non-LR installation's radio mode merely because one new LR product has been added.
Send these details to Tedson
Send the luminaire/driver model and datasheet, quantity, required functions and details of any existing Casambi or DALI system. For LED strip also provide voltage, watts per metre, length and channel count. The module, power supply and controls can then be assessed together.
When extending an installation, check the new luminaire or module against the existing network. Two Casambi products can serve different loads and offer different controls even when they can operate in the same network.
