Casambi CCT 2CH: smart LED controllers for dynamic white

BLE tunable white drivers and dimmers with 2-channel Casambi control

Standard

The Casambi CCT 2-channel dimmer drivers and controllers allow wireless adjustment of the correlated color temperature (CCT) and brightness of WW/CW (warm/cool) bi-channel LED loads via Bluetooth Low Energy (BLE) in a mesh topology. Management is done via the Casambi app (iOS/Android) with full support for scenes, timers, automations and local/offline control. Versions are available with 12/24/36/48 V DC and 110/220 VAC input, with constant voltage (CV) or constant current (CC) outputs.

System architecture

• Casambi CCT 2CH: compact/flush modules for independent control of the two WW/CW LED channels and dynamic white mixing.
• Compatible drivers: CV/CC versions with DC or AC supply.
• Gateway: for remote access, time synchronization, and cloud integrations when required by the project.
• Wireless controls: managed via Casambi mobile app, wall panels, battery-powered switches, or remote controls.
• Casambi Push Button Coupler: enables the use of traditional push buttons for local dimming control.
• Sensors: presence and light sensors for automatic on/dimming logic.
• Multiprotocol integration: through bridges/converters, existing networks/protocols (e.g. 0–10V, DALI, DMX) can be interfaced in hybrid systems.
• Mesh topology: node-to-node routing with typical indoor coverage of ~10–30 m per hop.

Advanced features

• Precise dynamic white control: continuous mixing between warm/cool channels for any intermediate shade (Tunable White).
• Dim-to-Warm curves: warm fading simulating halogen sources (warmer at lower brightness).
• Channel calibration: WW/CW balancing with configurable min/max limits and customizable power-on state.
• Security: access managed via app with permission levels and credential protection.
• Fast pairing: simplified commissioning via app with automatic node detection.
• System modularity: easy expansion by adding drivers and control devices.
• Deep dimming <1%: WW/CW mixing with a uniform curve free of perceptible flicker.
• Scenes and automations: schedules, fade, ramp, sunrise/sunset, and calendar programming.
• Reliable network: BLE mesh with self-healing paths and local operation even without data connection.
• High-frequency PWM: typically 250–500 Hz (entry), 1–4 kHz (mid), 8–16 kHz (high-end) depending on driver; suitable for photo/video.
• OTA: firmware/parameter updates and configuration backup/restore via app.
• Circadian scenes: day/night routines and light recipes for visual comfort and productivity.
• Efficiency and lifespan: optimized power consumption, reduced thermal stress, and extended LED life.

Typical applications

• Circadian cycles: wellness-oriented clinics/spas, medical practices, wellness centers with adaptive lighting.
• Smart residential: bedrooms, living rooms, kitchens with “activity”/“relax” scenes.
• Hospitality: B&B/hotels with customized scenes and simple local management.
• Retail: shop windows and corners with dynamic white for color rendering and atmosphere.
• Offices and studios: workstations and meeting rooms with dynamic CCT for comfort and productivity.
• Exhibitions: CCT modulation to enhance materials and artworks.
• Small/medium installations: wireless retrofit without proprietary wired buses.

Available types

• Casambi CCT 2CH: digital two-channel control for warm/cool white via Casambi BLE protocol.
